The Woman in Cabin 10 by Ruth Ware
Lo Blacklock is a travel writer who gets the gig of a lifetime: a one-week stay on a luxury cruise. After days of sleeping in a lavish cabin, eating fine cuisine, and conversing with impressive guests, Lo thinks that nothing can rock the boat. But when a storm hits, Lo sees a woman thrown overboard. Only, the next morning . . . all of the passengers are accounted for. Did the rain blur her vision or was someone really murdered? And if they were, who was it? Why were they killed? And why is Lo the only one who seems to care? Find out all of the answers when you read Ruth Ware's The Woman in Cabin 10.
