Chicago in the dead of winter can be brutal, especially when you’re scouring the frigid streets for a missing girl. Fifteen-year-old Ramona Titus has run away from her foster home. Her biological mother, Leesa Evans, is a recovering addict who admits she failed Ramona often in the past. But now she’s clean. And she’s determined to make up for her mistakes—if Cass can only help her find her daughter...Ramona is holding secrets dark enough to kill for, and anyone who helps her may be fair game. And if Ramona can’t run fast enough and hide well enough to keep the truth safe, she and Cass may both be out of time.
