I avoid most vampire stories, let alone a vampire story with any kind of love, friendship and romance in it. Usually too far fetched or sappy. However, I found, Let the Right One In a great read even without the horror parts. It is a good tale about adolescence, the supernatural and friends.
Meet Oskar, a shy, imaginative 12 year old boy of a single mom. Typical target for high school bullies. The poor guy is constantly ridicule and beaten to the point where he literally wets himself. Enter the weird girl next door, Eli and her weird "older relative." Oskar soon makes an awkward friendship with this girl-next-door. He finds that, in many ways, she is the least mixed up character in his life. Meanwhile, Oskar's neighborhood, a bleak, low-income area, soon becomes a worse place to live when people start disappearing or dying in gruesome ways.
Oskar suspects something odd, even wrong about his new friend. He soon realizes something is dangerous about her constantly changing health, expressions and the way that she asks him "Can I come in?" Yet, from knowing her, he gains an independence, strength and courage that he never knew before. He begins to see the inadequency of the police, the neighborhood drunks, the school and his own separated parents. With the social pressures, threats from bullies and despair with his parents, Oskar starts realizing the worth of a true friend, human or otherwise.
