This is one of the best books I have ever read. I would give someone my kidney for the chance to read it for the first time once again. It's sappy and romantic and most importantly it is queer.
You get to see their relationship develop from strangers to friends to crushes and beyond, it is kind of slow in the beginning but then you get to see them fall head over heels and you get to fall with them.
In addition the book is beautifully illustrated.

The first half of the book is completely lacking plot, grammatic rules and seemingly also logic. It is an incoherent mess of metaphors and similes. It sounds like it is written by a fourth-grader who thinks not using adjectives makes them seem smart. It took me three times to be able to read the whole book because it was so exhausting to read. The second half is ok, it's action-packed and romantic. However, there is a lot of unneeded sex scenes.
