i would recommend "John dies at the end" by David Wong of cracked.com fame
its horror and comedy all in one brilliant package, look it up ^~^

The terror is rooted in a substance known as soy sauce, a paranormal psychoactive that opens video store clerk Wong's—and his penis-obsessed friend John's—minds to higher levels of consciousness. Or is it just hell seeping into the unnamed Midwestern town where Wong and the others live? Meat monsters, wig-wearing scorpion aberrations and wingless white flies that burrow into human skin threaten to kill Wong and his crew before infesting the rest of the world. A multidimensional plot unfolds as the unlikely heroes drink lots of beer and battle the paradoxes of time and space, as well as the clichés of first-person-shooter video games and fantasy gore films. Sure to please the Fangoria set while appealing to a wider audience, the book's smart take on fear manages to tap into readers' existential dread on one page, then have them laughing the next.

also "Kafka on the shore" by Haruki Murakami

Joining the rich literature of runaways, Kafka On The Shore follows the solitary, self-disciplined schoolboy Kafka Tamura as he hops a bus from Tokyo to the randomly chosen town of Takamatsu, reminding himself at each step that he has to be "the world¹s toughest fifteen-year-old." He finds a secluded private library in which to spend his days--continuing his impressive self-education--and is befriended by a clerk and the mysteriously remote head librarian, Miss Saeki, whom he fantasizes may be his long-lost mother. Meanwhile, in a second, wilder narrative spiral, an elderly Tokyo man named Nakata veers from his calm routine by murdering a stranger. An unforgettable character, beautifully delineated by Murakami, Nakata can speak with cats but cannot read or write, nor explain the forces drawing him toward Takamatsu and the other characters.
