The bone dragon - Alexia Casale

Evie's shattered ribs have been a secret for the last four years. Now she has found the strength to tell her adoptive parents, and the physical traces of her past are fixed - the only remaining signs a scar on her side and a fragment of bone taken home from the hospital, which her uncle Ben helps her to carve into a dragon as a sign of her strength.
Soon this ivory talisman begins to come to life at night, offering wisdom and encouragement in roaming dreams of smoke and moonlight that come to feel ever more real.

As Evie grows stronger there remains one problem her new parents can't fix for her: a revenge that must be taken. And it seems that the Dragon is the one to take it.
This subtly unsettling novel is told from the viewpoint of a fourteen-year-old girl damaged by a past she can't talk about, in a hypnotic narrative that, while giving increasing insight, also becomes increasingly unreliable.

A blend of psychological thriller and fairy tale, The Bone Dragon explores the fragile boundaries between real life and fantasy, and the darkest corners of the human mind.
