The Woman in Cabin 10, the “tense, twisty delight” (Angela Clarke) by New York Times-bestselling author Ruth Ware, is available on a Kindle Monthly Deal for the whole month of April. Grab it here for only 99p.

A passenger is missing… But was she ever on board at all?

This was meant to be the perfect trip. The Northern Lights. A luxury press launch on a boutique cruise ship.

A chance for travel journalist Lo Blacklock to recover from a traumatic break-in that has left her on the verge of collapse.

Except things don’t go as planned.

Woken in the night by screams, Lo rushes to her window to see a body thrown overboard from the next door cabin. But the records show that no-one ever checked into that cabin, and no passengers are missing from the boat.

Exhausted and emotional, Lo has to face the fact that she may have made a mistake – either that, or she is now trapped on a boat with a murderer…

Ruth’s latest novel, the murder mystery thriller The It Girl, is also out now in paperback. Buy your US copy here and pre-order your UK copy here.
