Two young women are trapped in a deadly chase through the beautiful, dangerous waters around Australia in the new thriller from the bestselling author of Our Little Secret—perfect for fans of The Woman in Cabin 10 and The Drowning Woman. Ivy is in trouble. A recent break-up has left her humiliated and raw, so when her best friend, Regan, offers her a month-long escape in the form of a trip to Australia, it feels like a lifeline, one that Ivy grabs with both hands. Regan is everything Ivy’s not—confident, free-spirited, charismatic—and a natural at backpacker fun. But Ivy is drawn to a calmer type of holiday, so when she spots an ad for crewmembers on a small yacht being sailed by a doting father and his daughter, the girls decide to take the job. Together with a handsome third crewmember, they set off north into tropical heat, but it’s not long before doubts start to creep in. Are the girls simply claustrophobic on the boat, or have they stumbled into something they don’t understand? Tensions rise as the past threatens to catch up with them, and dark secrets emerge that will change everything. A dangerous cat-and-mouse game on land and at sea, this fast-paced, twisty thriller keeps you guessing until the very last page.
