It was supposed to be the party of the century: miles of idyllic white sand beaches, lush jungle foliage...and a dark legend nobody dreamed might be all too true. When an online influencer and several hundred of his most loyal fans land on Prosperity Island, the plan is simple: five days of elaborate games, drinking, and suntanned fun. A week in paradise should have been a welcome respite. The only survivor of an infamous cult, Ruth wants nothing more than to keep her head down and not draw attention. She's spent decades outrunning her blood-soaked childhood, and her identity is a closely held secret. But then the true history of the island is revealed…along with its sinister connection to Ruth's past. As guests go missing and games turn deadly, Ruth and the rest of the attendees are forced to question whether they've really been invited to paradise...or whether something much darker―and far bloodier―is waiting for them just beyond the bonfire's light.
