The Stranger on the Train by Abbie Taylor

Single mother Emma is exhausted caring for her one-year-old son, Ritchie. When he is kidnapped by a woman that helped Emma with him on the London underground, Emma has a hard time convincing the authorities about the truth of what happened--they wonder if Emma harmed Ritchie and is making up lies to cover up her crime. However, Emma has an ally in Rafe, who believes she's telling the truth. Will Emma, with Rafe's help, be able to find Ritchie and bring him home?  Recommend The Stranger on the Train to readers who've enjoyed Close My Eyes by Sophie McKenzie and Lullaby by Claire Seeber. It will be published in May.
