Gwen Turner has made a bloody mess of her life. She recently broke up with the best man she's ever known for reasons she can't even admit to herself and quit a lucrative job to open her own coffee shop. To top it all off, her best friend is getting married and leaving her behind in singlehood.

Along with too much cheap wine and bad reality TV, Gwen turns to a dating app to help fill the void in her life. Swiping through the few eligible bachelors left in town, she spends her evenings out on one disastrous date after another. But when a string of murders suddenly occurs in her small coastal English city, she's shocked by the connection between each of the victims--they've all been on a date with her.

Before she knows what's happening, Gwen finds herself the main suspect in a serial killer's murderous spree, and the only way she can clear her name is to track down her former dates (even those that have ghosted her) and unmask a killer before it's too late.
