"The estranged best friend of a missing heiress races to unravel the secrets behind her disappearance-with the only clues left behind in a manuscript detailing her possible last days-in this gripping psychological thriller. Abby and Gia have been friends since they were thirteen, when Abby's mom came to work for Gia's billionaire family as a chef. Five years later, the two were forever bound by tragedy when Gia saved Abby from an attack by Gia's stalker, killing him in the process. In the aftermath, Abby threw herself into her studies while Gia wrote a somewhat embellished memoir about that fateful summer. And ever since Gia got married and inherited a remote mansion in the Greek islands, she and Abby haven't talked much. But when Abby receives an invitation from Gia to see the Northern Lights in Sweden for her thirtieth birthday, first-class airfare and five-star accommodations included, it's almost impossible to resist. Especially since Gia's crush-worthy brother Benny-Abby's "one who got away"-will also be there. The invite is soon followed by a mysterious, threatening email in Abby's inbox. Suddenly a trip out of town isn't such a bad idea. Abby and Benny arrive together at the Swedish resort only to discover Gia isn't there. As the days pass with no word, they get worried enough to fly to Greece to find her themselves. In their search through Gia's eerily empty beachfront estate, they find no sign of her except a new manuscript, penned by Gia in the months leading up to her disappearance. The pages reveal tales of Gia's luscious new marriage and the wealthy young couple they entertained with fizzy champagne under the hot Mediterranean sun. Indulgent luxury at its finest-until Gia's plot turns. As money troubles arise, Gia feels less and less safe in her own home. Who are their guests, really? The pages end abruptly, leaving Abby and Benny with more questions than answers. But given her previous use of artistic license, can they believe what they read? And, more important, where is Gia now?"-- Provided by publisher.
