Let the Right One In
by John Ajvide Lindqvist
Oskar doesn't have many friends. So when Eli moves in next door, things seem to be improving. She's a little strange, and her 'father' is frankly sinister, but at least she likes Oskar. Then a child's body is found hanging from a tree, and all hell breaks loose. Is it a serial killer? Or something a bit...different?
