Elf Girl and Raven Boy, book 1: Fright Forest
Marcus Sedgwick2012

Raven Boy has short black spiky hair, amazing night vision and can talk to animals. Elf Girl is light of foot, sharp of mind and...elfish all over. She hadn't expected to meet Raven Boy; it's not that often someone falls out of the trees and squashes your home flat like Raven Boy did.
Before they know it they are plunged into some very strange, creepy, altogether spooky and hilarious adventures as they save their world from trolls, ogres, witches and things that slither and slide in the fiendish forest.
