I've created two Kindle books using public domain works, The Sea-Wolf by Jack London and The Legend of Sleepy Hollow & Rip Van Winkle by Washington Irving, respectively. Each feature original illustrations.
Amazon has some unfortunate quirks that have scattered the location of these books. A link for the physical copy of The Sea-Wolf is here, with the wrong Kindle link attached to it. The link for the Kindle version of The Sea-Wolf is here, with the wrong physical copy linked. The Kindle version of The Legend of Sleepy Hollow & Rip Van Winkle is available here with some random physical copy attached to that entry (the physical copy of my version has not been made available).
I also worked on a commissioned book called "How to Be a Girlfriend" when I worked for the Barnes & Noble website Sparklife. The book did not end up getting produced.
In 2014 I illustrated a book proposal written by my friend, Emily Winter, for Barnes & Noble. The deal fell through when there was a change of editors, but the book, How to be a Girlfriend, was going to be a tween-centered instructional guide full of tips on how to handle your first real relationship. What to look for, what's healthy, what not healthy, what to expect. It was cute.
