Extraordinary birds - Sandy Stark-McGinnis

Eleven-year-old December knows everything about birds, and everything about getting kicked out of foster homes. All she has of her biological mum is the book she left behind, The Complete Guide to Birds, Volume One, and a photo with a message: 'In flight is where you'll find me.' December knows she's truly a bird, just waiting for the day she transforms and flies away to reunite with her mum. The scar on her back must be where her wings have started to blossom - she just needs to practise and to find the right tree. She has no choice; it's the only story that makes sense.
When she's placed with Eleanor, a new foster mum who runs a taxidermy business and volunteers at a wildlife rescue, December begins to see herself and what home means in a new light. But the story she tells herself about her past is what's kept December going this long, and she doesn't know if she can let go of it ... even if changing her story might mean that she can finally find a place where she belongs.
