From the publisher:

"None of us can leave."

"Early morning on a perfect summer's day, people begin to descend on an idyllic, secluded beach. Amongst their number, a family, a young couple, a refugee and some American tourists. Its fine white sand is fringed with rock pools filled with crystal clear water. The beach is sheltered from prying eyes by green-fringed cliffs that soar around the cove. But this utopia keeps a dark secret.

A woman's body is found floating in the waters, which brings these thirteen strangers together to try and unravel the riddle of the sands and escape the beach alive in this tense, fantastical mystery."
