Once upon a time, a madman tried to murder Emma Stapleton on a perfectly normal school day. And, the unlikeliest of classmates came to her rescue: her nemesis. Ten years later, her nemesis is dead, her school sweetheart divorced her, and she's no closer to catching that madman. Emma's goal to set things right hasn't panned out as planned. Now, she just wants to leave her position as Investigator for the Metropolitan Police Services and forget everything. But, life has other plans. When her haunting past comes barreling into her present, the one bright spot in her life is that Emma might finally put the past to bed once and for all, even if its face turns out to be shockingly, and impossibly, familiar.
