Heather Burnside is back with this completely unputdownable, heart-racing series, perfect for all fans of Kimberley Chambers and Martina Cole.

Sophie and Kelsey have always had each other. When their mum is diagnosed with cancer and their dad fails to step up, they're forced to move into the care system. But Sophie knows they'll be okay as long as she's there to protect her sister. But when Kelsey is found a foster family and Sophie can't join her, Sophie's left in an unsafe situation in the home, forced to do things against her will. Finding her own foster family feels like a relief, but it's short lived when her trust in her new foster parents is betrayed. With nowhere to turn, Sophie finds herself homeless. But when she finds her new street family, Sophie joins the working girls and her new identity as Sapphire is complete.
