The Birthday Girl

Mona is a carefree artist staying at the island's upscale hotel to work on her illustrations. Beth is the harried mother of a toddler, on the island for a weekend escape with her family. Charlotte wanted a romantic getaway with her husband, not a trip with his troubled teenage stepdaughter. One of them is a serial killer who poisoned four of the girl's friends at her eleventh birthday party. Three guests who fit the profile. Cut off from the mainland and isolated on a remote Welsh island, former detective-turned-hotel-manager Mallory Dawson will have to figure out whodunit before the killer risks everything to attack again.

An absolutely gripping Welsh crime novel, perfect for fans of Sarah Pearse and Lucy Foley.
