In 1970, a popular, wealthy student, Hélène Prince, fell to her death just before her graduation from Pelham College. The police ruled it a suicide, but Prin's twin sister never believed the official account of the events. Thirty years later, now an internationally known bestselling suspense writer, she's still yearning for an answer.

Enter Faith Fairchild, a caterer, sometime sleuth, and, most significant in this case, the sister of a Pelham grad. Through the Pelham old-girl network, Faith has been hired for a weeklong reunion of eight classmates on the novelist's very private island. The dream job-;the house is a mini-resort with spectacular ocean views-;turns into a nightmare when Faith discovers she's trapped not with a group of longtime friends, but a group of suspects. None of the women knew the others were invited-;and definitely hadn't stayed in touch. With no phone lines, cell reception, or boat, Faith is caught up in a deadly game of cat and mouse as one by one the alumnae fall prey to a madwoman. A disturbed sister's revenge? Faith must quickly unlock a series of past secrets if she's going to leave the island alive!
