About the Book: When All Her Fault opens, Marissa Irvine arrives at 14 Tudor Grove to collect her young son Milo from his first playdate—only to learn a woman she doesn’t recognise answered the door, and Milo is gone. As suspicion shifts among the four women closest to the event, they each become suspects in a tight-knit Dublin neighbourhood brimming with secrets. In the end, only one may have taken Milo—but all could be blamed.
