Splinters of Sunshine by Patrice Lawrence

From the multi-award-winning author of Orangeboy, comes a YA road-trip mystery.

After a fun Christmas Eve decorating the tree and singing along with his mum to Queen, fifteen-year-old Spey wakes up on Christmas morning to find the ex-prisoner father he's never met asleep on the sofa. Then he receives a mysterious package in the post: a torn envelope filled with half a collage he made with his old friend Dee on her sixth birthday.

Dee bounced between schools and pupil referral units until a tragedy meant she ended up in care outside of London, drawn into the world of county lines gangs. They haven't spoken for years, but Spey is sure she must be in danger. He just doesn't know where she is.

There's only one person Spey can think of who might be able to help ... On a roadtrip like no other, can Spey and his dad find Dee, and will they be ready to confront a criminal gang together?
