Although her childhood was haunted by a famous crime, Rhinannon’s life is normal now that her celebrity has dwindled. By day her job as an editorial assistant is demeaning and unsatisfying. By evening she dutifully listens to her friend’s plans for marriage and babies whilst secretly making a list. A kill list. From the man on the Lidl checkout who always mishandles her apples, to the driver who cuts her off on her way to work, to the people who have got it coming, Rhiannon’s ready to get her revenge. Because the girl everyone overlooks might be able to get away with murder.

The night after her father's funeral, Claire meets Lucas in a bar. Lucas doesn't know it, but it's not a chance meeting. One thoughtless mistyped email has put him in the crosshairs of an extremely put-out serial killer. But before they make eye contact, before Claire lets him buy her a drink—even before she takes him home and carves him up into little pieces—something about that night is very wrong. Because someone is watching Claire. Someone who is about to discover her murderous little hobby.

Have you ever walked home at night, keys in hand, ready to throw a punch in self-defence? That’s how it all started. The killing spree, I mean. I sort of tripped into this role. Literally. The first one was following me. That guy from the nightclub who wouldn’t leave me alone. I pushed him, he stumbled, and fell onto his own broken wine bottle. Oops. It was such a waste of a good house white. But now I can’t seem to stop and nor do I want to, I’ve got a taste for revenge and quite frankly, I’m killing it.

Grim Wolds, England: Winifred Notty arrives at Ensor House prepared to play the perfect governess—she’ll dutifully tutor her charges, Drusilla and Andrew, tell them bedtime stories, and only joke about eating children. But long, listless days spent within the estate’s dreary confines come with an intimate knowledge of the perversions and pathetic preoccupations of the Pounds family—Mr. Pounds can’t keep his eyes off Winifred’s chest, and Mrs. Pounds takes a sickly pleasure in punishing Winifred for her husband’s wandering gaze.

Quinn Maybrook and her father have moved to tiny, boring Kettle Springs, to find a fresh start. But what they don’t know is that ever since the Baypen Corn Syrup Factory shut down, Kettle Springs has cracked in half. On one side are the adults, who are desperate to make Kettle Springs great again, and on the other are the kids, who want to have fun, make prank videos, and get out of Kettle Springs as quick as they can.
