Infinity: Chronicles of Nick (#1) by Sherilyn Kenyon
Nick gets beat up by his friends and wants revenge. After a stint in the hospital, he starts working for Kyrian Hunter, who isn't what he seems. Suddenly he learns more about the world around him, more than he expected.
I really enjoyed this book. Nick has tons of sarcastic comments (which is great). His world is basically not what he thinks but he keeps his strong attitude and finds his sense of right. The characters are well developed. I loved the Simi character. She has a crazy speech pattern and is just all around funny!
