Warning: The language used in quite adult and there is graphic violence (albeit, in black and white). Nothing that a typical adolescent boy isn't already reading (and in color), but it may not be suitable for the very young.
Book Description
Frank Armstrong has an inoperable brain tumor that’s killing him. In his final days, with his body, senses, and mind failing him, he’s going to do the one thing that he’s never been able to do before… save the girl.
Update: Chapter 3 is now available and is the same 99 cents as Chapter 2. We'll have to wait until next month to get the next part of the story.
In the meantime, Fialkov's short story Belly Button Reset ($0.99) was submitted two days later (according to the publication dates), but is already available. They must be checking the graphic novels by hand and have a more automated system to check text based books.
Update: You can now get this and another a short story written by Fialkov, Half a Person, for free from Feedbooks. Just follow the links and select the Mobipocket/Kindle version.
