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.
