From the author of This Books Kills and Catch Your Death comes a new novel filled with murder, mystery and mind-blowing twists, perfect for fans of Holly Jackson and Karen M. McManus.

It’s been one year and six days since seventeen-year-old Kay left her sleepy hometown after the devastating death of her best friend, Ivy. But now she’s back, forced to stay with her cousin as her parents jet off to a holiday without her. She was hoping for a quiet week of boredom and memories, but what actually greets her is a terrifying anonymous letter left on her bed.

The note tells her that there will be a thrill on Tuesday, a wreckage on Wednesday, treachery on Thursday, a fire on Friday, sabotage on Saturday, a stabbing on Sunday…and her murder on Monday.

As the events threatened in the letter start to happen, Kay knows she has to figure out who her would-be murderer is before they can follow through on their twisted promise and make the worst day of the week a deadly one.
