''ComicBook/IKillGiants'' is a graphic novel written by Joe Kelly and illustrated by JM Ken Niimura.

Barbara Thorson is a loner. A misanthrope. A girl with a very caustic personality. And she's only in the fifth grade. Oh, yes, and she kills giants.

Problem is, nobody else sees what she sees. Everyone treats her as a freak, and she reacts violently to the counselor, Mrs. Molle, when she tries to find out a little more about Barbara. It takes the friendship of a new girl in town, Sophia, to start breaking Barbara out of her shell....

But is that for the best? Are the giants Barbara claims to kill really real? Is Barbara really just suffering from some kind of mental breakdown, caused by some kind of family trauma? And what does baseball have to do with it?

An excellent work, ''I Kill Giants'' starts weird, gets crazy, then gets CrazyAwesome, and then goes straight into heartwarming. Read it if you need something to read.

It doesn't help that the art style is a little similar. The headbands also help to visually distance her from all the other characters and emphasize how much of an outsider she is.
* WeaponOfChoice: Coveleski.
