Announcing my new book series, InvestiGators! Here's the official synopsis:

Meet the InvestiGators. With their gadgets, know-how, and super-fast transportation system (they flush themselves down toilets to speed through the sewers!) Mango and Brash are the scourge of the super villain landscape! As vest-wearing employees of the Special Undercover Investigation Teams, they solve all kinds of mysteries and frequently butt heads with their arch-nemesis: a former agent known as Crackerdile.

Riddled with puns, potty humor, absurdism, and hilarious twists, InvestiGators is the perfect series for Dog Man fans looking for their next great read! It’s kid-friendly comics at their best.

The first book comes out on February 25th, 2020—so a few months after the second Kitten Construction Company book, A Bridge Too Fur. And like that series, it is also from First Second Books. You can read a little bit of what I've had to say about the series at Paste Magazine, here:

Ha, only one year since my last update, so I'm getting better. The cover so the second Kitten Construction Company book, A Bridge Too Fur, has been revealed! This time Marmalade and the other House Kittens have to get used to working with DOGS! It comes out October 2019 from First Second Books, and as usual you can pre-order it from the Macmillan website. I'm also working on an exciting new series which will hopefully be announced soon.


Yes, yes, it's been nearly two years since I last updated my website, but now you can see what I've been working on! My newest book is Kitten Construction Company: Meet the House Kittens (click the title to see a few preview pages, or to pre-order it from the retailer of your choice.) It comes out on September 4th, 2018, from First Second Books! It's also the first in a series, and I'm working on the second book right now. Here's the cover:


My latest book, Hippopotamister, comes out on May 10th, 2016, from First Second Books! It's my first graphic novel for younger readers as both writer and artist. Here's the cover:

Here are some nice things being said about it:

"Clever and fun!" —Raina Telgemeier, author of Smile

"Hip, hip, hooray for Hippopotomister!" —Lauren Castillo, author of Nana in the City

"Delightfully sweet. Three cheers for Hippopotamister!" —Jennifer & Matthew Holm, co-creators of Babymouse & Squish

"At it's core, Hippopotomister is a touching friendship tale in the tradition of Frog and Toad and Robot Dreams. But this book will also serve as the perfect roadway for those kids looking for a path from picture books to graphic novels." —Nick Bruel, creator of the Bad Kitty series

"Green’s (Teen Boat!) characters burst with personality, his comedic sense shines, and his visual storytelling skills are solid." —Publishers Weekly, starred review

"A charming book with a solid message about changing one's life through hard work, imagination, and openness to new experiences." —Kirkus Reviews

"A fun and engaging selection for readers just venturing into graphic novels." —School Library Journal

There is a book release event in Manhattan on May 17th at Books of Wonder (click for details.) You can also order the book from IndieBoundBarnes & Noble, or Amazon. I'll be doing school and library events, as well as a number of conventions, throughout the year. For the most up-to-date info check my Facebook and Twitter!

5-3-15 has announced that Teen Boat! The Race for Boatlantis, the anticipated sequel to the 2012 graphic novel, Teen Boat!, has begun serializing online starting, in advance of its fall print release.

Teen Boat!, written by New York Times-bestselling author Dave Roman and illustrated by John Green, is the only comic about a high school student with the unique ability to transform into a small yacht. As Teen Boat nears graduation, his focus is divided between two events: a boat race that holds the key to the mysterious city of Boatlantis, where boats are at the top of the social ladder, and the senior prom. Can Teen Boat win the race AND the heart of his dream girl, the foreign exchange student Niña Pinta Santa Maria?

The all-new, full color, 160-page graphic novel comes out September 1st, 2015, but you can start reading it online now at

You can also pre-order the book from IndieBoundBarnes & Noble, or Amazon

ISBN 978-0-547-86563-8


I know I am behind in keeping my website up to date, and I'm certainly late with this announcement, but it will at least be exciting news for a while:

Written by New York Times-bestselling author Dave Roman and illustrated by John Green,
Teen Boat! is the story of a boy with the power to transform into a small yacht!

From breaking out in barnacles to facing pirates and detention, all the challenges of adolescence are given a nautical twist.

Being a teen and being a boat means dealing with a lot of pier pressure!

This full color, 144-page graphic novel collects the Ignatz Award-winning mini-comic plus over 50 pages of new comics and bonus material.

ISBN 978-0-547-63669-6


I added another PlayStation HOME event I worked on to my GAMES page. This one is the DEMON GOURD, naturally for Halloween.


After a year hiatus I will be attending San Diego Comic-Con again, July 21-25. I will be at the Comics Bakery table in the Small Press area. It's table L-06, which can be found somewhere on this map:

I will have original pencil pages of the Phineas & Ferb comics I've been doing for Disney, and I should also have the first two Junior Graphic Novels that I've adapted (which can also be found on Amazon HERE and HERE.) I will also have the new Space Office #2 mini-comic, plus Teen Boat and Jax Epoch comics. And on Sunday at noon I'll be on a panel with Dave Roman and Raina Telgemeier doing some fun interactive comics making stuff.

In other news, PUZZLE BOTS has been accepted into the PAX 10! So I will be attending PAX Prime in Seattle in September along with the game's designer, Erin Robinson.


I've updated my site! Most of the new content can be found in the GAMES section. There are screenshots of some games I've recently worked on, plus videos of stuff I've worked on for Sony PlayStation Home. I also added handy links to PDFs of my resume and portfolio at the top of this page.


Deja vu! Again it's been almost a year since an update! As usual, I've been very busy. Over the Summer I colored background art for one adventure game which is still pretty much under wraps, and I've also been doing the background art for PUZZLE BOTS, an adventure game which should come out late this year. Since the Spring I've also had a day job where I'm Senior Lead Concept Designer. Sounds impressive, but I can't say too much about it other than if you have a PlayStation 3 and go into Home you might come across some of my creative this Halloween. It's a real stretch from my own work like NEARLY DEPARTED. Speaking of Halloween and zombies, I've decided to release an in-progress build of Nearly Departed so far. The game is still incomplete, and there are still some weird quirks to it (after playing awhile, animations start to play out of sync and dialog gets skipped, but the game is still playable, up until the point where you'll get "that part of the game is incomplete" messages.) You can find a new download link at the NEARLY DEPARTED page. Hopefully I'll have another update sooner rather than later but my track record certainly speaks against me.


Wow, it's been almost a year since an update! Well, that can only mean I've been busy. And since I am updating, that means I can finally talk about the confidential project I've been working on all this time. I've been doing artwork for a computer game that will be coming out in a few months, and you can read all the details and see screenshots in my GAMES section.


Uploaded a portfolio PDF with some of my various comic-based work (art, letters, colors, book design, that sort of thing).


I made a teaser trailer for my zombie adventure game. You can see it at the NEARLY DEPARTED site, in the NEWS section.


I've started posting my new comic SPACE OFFICE online. You can read the latest installment at WebComicsNation HERE. I also made a minor news update to my NEARLY DEPARTED site, mentioning some recent progress on my game.


I've updated by GAMES section with character designs and other miscellany.

In other news, Disney Adventures Magazine has been cancelled, which means I'm no longer the Comics Consultant for the publication. This will certainly free my schedule a bit to work for other clients, so anyone who's interested please check out my SERVICES page to see what I can do.


I'm back from Canada where I had a great time and met some great people. No big updates to the site just yet, but I'm still hard at work at the third Jax Epoch trade paperback, Teen Boat, and my game Nearly Departed. Check out my blog for any other news!


I'll be at San Diego Comic-Con from July 25th-29, at table P2 (The Comics Bakery) in the small press area. I'll have my new mini-comic, Space Office, among other things. After Comic-Con, I'll be at the Toronto Comic Art Festival, August 18 and 19th.


I know there haven't been any updates in a long time, but I've been quite busy. I'm getting ready for the MoCCA Artfest this weekend, where I'll be at the Comics Bakery (tables A7 and A8). Debuting at the show is issue 7 of TEEN BOAT, a preview of Jax Epoch and the Quicken Forbidden Volume 3, and a few other goodies.

I also recently visited my high school to see the restoration of the mural I painted senior year. You can read about it and see pics HERE.


I've redone my website! Most of it is still under construction, so you can check out the old site HERE.
