Sadie loves her daughter and will do anything to keep her safe.
She can't tell her why they had to leave home so quickly - or why Robin's father won't be coming with them to London.
She can't tell her why she hates being back in her dead mother's house, with its ivy-covered walls and its poisonous memories.
And she can't tell her the truth about the school Robin's set to start at - a school that doesn't welcome newcomers.
Sadie just wants to get their lives back on track.
But even lies with the best intentions can have deadly consequences...
