Camilla Läckberg's The Fjällbacka Murders (2012 - 2014)

Erica Falck, a successful crime writer and mother of three, moved with her husband and children from the city to her hometown of Fjällbacka, a fishing village on a picturesque island off the coast of Sweden. Her return seems idyllic, but simmering beneath the village's surface lie hidden secrets, twisted desires and deceit waiting to erupt into the ultimate sin - murder.
