"In Baxter's Beach, Barbados, Lala's grandmother Wilma tells the story of the one-armed sister. It's a cautionary tale, about what happens to girls who disobey their mothers and go into the Baxter's Tunnels. When she's grown, Lala lives on the beach with her husband, Adan, a petty criminal with endless charisma whose thwarted burglary of one of the beach mansions sets off a chain of events with terrible consequences. A gunshot no one was meant to witness. A new mother whose baby is found lifeless on the beach. A woman torn between two worlds and incapacitated by grief. And two men driven into the Tunnels by desperation and greed who attempt a crime that will risk their freedom -- and their lives.
