MISSING SISTER
Book Summary
In this gripping sequel to the bestselling young adult thriller Girl, Missing, Lauren, now sixteen, is reeling from academic pressure and a recent family tragedy. Hoping for some respite, her biological mother takes her on vacation along with her two sisters. However, the past returns with a vengeance when one of them disappears under circumstances hauntingly similar to those Lauren experienced years ago. Too similar to be a coincidence. Now, Lauren must confront her own ghosts to prevent the nightmare from repeating itself and to save her sister.
What is it about?
Two years have passed since the events of Girl, Missing, but peace remains elusive for Lauren. Added to the pressure of exams is a recent loss that has left a deep mark on her and her family. Her biological mother, trying to steer her away from routine and pain, organizes a vacation for the three sisters. What was supposed to be a time to reconnect and heal turns into a new nightmare when one of them goes missing. The parallels with Lauren's own kidnapping are so obvious that it is impossible to attribute them to chance. The young woman will be dragged into a desperate investigation, where she must decipher whether the same danger is stalking them again or if a new predator has emerged from the shadows, forcing her to face her past to protect her family.
