In Santa Paloma it’s unwise to go to the lighthouse at night – because it’s deadly… Sleepy little Santa Paloma is a relaxed beach town with a lovely marina, a large retiree population…and a lot of very bad things, like murder…and worse. Geraldine and Nancy Fullerton share a granddaughter, Samantha – Geraldine through blood, Nancy through marriage to Geraldine’s ex. They also share a love of mysteries and are excellent partners in solving crime. Samantha Greene loves her grandmothers and their friends, and not only because solving mysteries that elude the police is their favorite hobby. But some crimes are more dangerous than others, and investigating a string of brutal murders puts them all on the killers’ radars, Samantha especially. A surfing drug dealer and his mule, a classical musician, wealthy and shady yacht owners, mixed martial arts fighters, and the leaders of Santa Paloma’s community are all potentially involved. But a homeless man could hold the key – or he could have imagined everything. But as more and more people die, Samantha knows one thing for sure – whatever’s happening, the lighthouse is involved. What Geraldine and Nancy know is that something wicked is going on – and they need to stop it before Samantha is the next victim.
