The Water Rituals (White City Trilogy Book 2)

HOW DO YOU UNMASK A KILLER WHO'S SPENT YEARS PREPARING TO HUNT YOU DOWN?
A pregnant woman has been murdered in a brutal, ritualistic way: burned, hung, and then placed upside down in a Bronze Age cauldron. When Unai “Kraken” Lopez de Ayala discovers the victim is his first love, Ana Belén Liaño, memories of their time together come flooding back, and with them reminders of a dark secret long buried. Then the killer strikes again, enacting the same ritual against a second expectant parent. Kraken knows he must confront his past in order to unmask this fiend. And there’s no time to waste, because Deputy Superintendent Díaz de Salvatierra has just found out she's carrying a child. And the father could very well be Kraken himself...
