Demon, boy, boy goes crazy at certain word after looking a demon in the eyes.

[Tysen]

I am looking for a book where a boy looks a demon in the eyes and he passes out, then the boy ends up in the hospital when he wakes up. Now, every time someone says a certain word, he goes crazy for a couple minutes. That's all I can remember.

What year did you read it, or about when was it published? Is it for children, YA, or adults? Is it horror, humor, something else? Author female or male? Remember the cover?

Read in about 2009, YA, action, cover had cars on it, the title was big and red
