Fifteen-year-old Meghan has been in and out of hospitals with a plague of unexplained illnesses. But when the ailments take a sharp turn, clashing medical opinions begin to raise questions about the puzzling nature of her illness. Doctors suspect Munchausen syndrome by proxy, a rare behavioral disorder where the primary caretaker seeks medical help for made-up symptoms of a child. Is this what's going on? Or is there something even more sinister at hand? Meghan's mother, Becky, must race against time to prove that her daughter has a deadly disease. But she first must confront her darkest fears and family secrets that threaten not only to upend her once-ordered life, but to destroy it.

Mackenzie Cooper took her eyes off the road for just a moment, but the resulting collision was enough to rob her not only of her beloved daughter but ultimately of her marriage, family and friends. Now she lives in Vermont under the name Maggie Reid. She’s thankful for the new friends she’s made, though she can’t risk telling them too much. But she isn’t the only one in this peaceful town with secrets. When a friend’s teenage son is thrust into the national spotlight, accused of hacking a powerful man’s Twitter account, Maggie is torn between pulling away and protecting herself --- or stepping into the glare to be at their side. As the stunning truth behind their case is slowly revealed, Maggie’s own carefully constructed story begins to unravel as well.
