One moment Juniper Reese existed, and the next she vanished into thin air. This is how it feels for Lavender, her twin, when she receives the call that Juniper didn't show up to her job one morning. Still adjusting to Juniper's cross-country move to run from the ghosts of their mother's death, Lavender knows something is wrong - but she also knows her sister is still alive. As she follows Juniper's footsteps in an unfamiliar town, she begins to uncover a plot that seems to suggest her sister was being stalked before her disappearance. Now it's on her to find Juniper before time runs out and convince those around her that her disappearance wasn't an attempt to "get away." What she doesn't know is that she's being watched by someone who just realized perfection came twice. He begins to hone in on Lavender, his attention never satisfied until he can have them both for himself. Will Lavender be able to find her sister before time runs out? Or will she be the next target in an obsession gone wrong?
