Where we belong / Catherine Ryan Hyde.

Angie has struggled since her father died, and with a mother barely making ends meet she often finds herself the sole carer for her younger sister Sophie. Sophie is autistic. She has severe learning disabilities, is unable to communicate and becomes extremely agitated. Angie and her family are on the brink of homelessness...again. With Sophie's shrieking, home never seems to last for long. But then they move in with Aunt Vi - across the fence from a hugh Great Dane. Sophie begins to imitate the dog's calm nature, and the shrieking stops. Everyone relaxes. Until Paul, the dog's grumpy, socially isolated owner, moves away - looking for a quiet retirement. Much to Angie's humiliation, her mum is determined to follow Paul and his dog - for Sophie's sake. Once reunited, Angie and Paul form the closest friendship either has known - and Angie is willing to risk everything - even her chance of a real home - to help Paul's dream come true.
