THE SECRETS SHE KEEPS Michael Robotham Sphere £19.99

HE has a popular series featuring criminal psychologist Joe O’Loughlin, but I thought his standalone thriller Life or Death was an absolute knockout. Now Robotham again shows he’s a powerful writer by packing this psychological thriller with dynamite shocks. Meghan and Agatha are both pregnant. They are strangers, but Agatha admires Meg from afar, avidly reading her blog about her perfect family and life. Agatha wants to be Meg. When the trajectories of their lives intersect, the explosive twists and turns will stun you.
