Adopting his late girlfriend's son turns one man's life upside down in this domestic thriller by the author of The Neighbors. When Josh's longtime partner, Grace, dies in a tragic accident, he is left with a mess of grief-and full custody of her seven-year-old son, Logan. While not his biological father, Josh has been a dad to Logan in every way that counts, and with Grace gone, Logan needs him more than ever. Wanting to do right by Logan, Josh begins the process of becoming his legal guardian-something that seems suddenly urgent, though Grace always brushed it off as an unnecessary formality. But now, as Josh struggles to find the paperwork associated with Logan's birth, he begins to wonder whether there were more troubling reasons for Grace's reluctance to make their family official. As he digs deeper into the past of the woman he loved, Josh soon finds that there are many dark secrets to uncover, and that the truth about where Logan came from is much more sinister than he could have imagined... Tightly paced and brimming with tension, Her Secret Son is a heartbreakingly honest portrait of a family on the edge of disaster and a father desperate to hold on to the boy who changed his life.
