Seventeen-year-old Nareeka "Niki" Gill grew up in the small town of Longrove, living next door to her beloved Aunt Sandra. She hasn't been back to the town, though, since Aunt Sandra's death three years ago - her parents wanted a fresh start. But with her mum and dad going on a weeklong cruise to celebrate their 20th wedding anniversary, she's staying for one week only, with her uncle and cousin, Rosie.
But when Niki arrives in Longrove on Monday, it is to find a threat has been left on her bed: Get ready for the next week because we're going to play a game. Can you beat me and figure out my identity before the week is up? The stakes will just keep getting higher - there's going to be a thrill on Tuesday, a wreckage on Wednesday, treachery on Thursday, a fire on Friday, a sinking on Saturday, a stabbing on Sunday - and your murder on Monday.
