From the New York Times bestselling author of The Flight Attendant comes a twisting story of love and deceit: an American man vanishes on a rural road in Vietnam, and his girlfriend follows a path that leads her home to the very hospital where they met.

Alexis and Austin don’t have a typical “meet cute”—their first encounter involves Alexis, an emergency room doctor, suturing a bullet wound in Austin’s arm. Six months later, they’re on a romantic getaway in Vietnam: a bike tour on which Austin can show Alexis his passion for cycling, and can pay his respects to the place where his father and uncle fought in the war. But then Austin fails to return from a solo ride. Alexis’s boyfriend has vanished, the only clue left behind a bright yellow energy gel dropped on the road.

As Alexis grapples with this bewildering loss, she starts to uncover a series of strange lies that force her to wonder: Where did Austin go? Why did he really bring her to Vietnam? And how much danger has he left her in? Set amidst the adrenaline-fueled world of the emergency room, The Red Lotus is a global thriller about those who dedicate their lives to saving people—and those who peddle death to the highest bidder.
