'A wonderful, artfully addictive novel' IAN MCEWAN When Jonah and Raff wake up on Monday, their mother Lucy isn't there. Although he's only nine, Jonah knows enough about the world to keep her absence a secret. If anyone found out she'd left them alone, who knows what could happen to him and his little brother? As the days go on, he puzzles over the clues left behind: who sent Lucy flowers? Why is her phone in a plant pot? Why are all her shoes still there? And who in their neighbourhood might know more about Lucy than he does?
