It's been five years since heiress Clare Monroe tragically died on New Year's Eve at her family's opulent Italian palazzo. Since that time, her college friends have harbored a dark secret--their lies and betrayals led to Clare's untimely death.

What happened that fateful night was a horrible accident, but Luca, Harper, Sirina, and David are guilty, nonetheless. And their desperate decision to conceal the truth destroyed their once-close bond.

Now, the estranged friends are each the recipient of an invitation from the Monroes to return to the lakeside palazzo for a long-overdue memorial for Clare. Accepting the Monroes' invitation means playing with fire, but they can hardly refuse.

Luca, Harper, Sirina, and David have barely settled into their idyllic accommodations on Lake Como before someone at the memorial party begins targeting them. Haunted by little "gifts" left in their rooms, taunting notes, and the unshakable sense of being watched, it soon becomes clear that someone on the guest list knows the whole truth about the night Clare died--and the secrets her friends have been keeping. Nothing is as it seems at the palazzo on the lake, and under their tormentor's vengeful gaze, their secrets--and their lives--are in danger.
