In 'A Study in Drowning' by Ava Reid, Effy Sayre’s world intertwines with fairy tales since her visions of the Fairy King followed her from childhood. Clinging to the epic story of Angharad, she enters a contest to redesign the house of Emrys Myrddin, the late author of the tale she cherishes. Amid the dilapidated Hiraeth Manor, Effy faces not just architectural challenges but clashes with Preston Héloury, a scholar bent on discrediting Myrddin. Together, they unravel the enigmatic legacy of the manor and its creator, navigating a labyrinth of deceit where magical and mortal dangers await. Their pursuit of the truth behind the myths they’ve held dear threatens to unravel not only Myrddin’s secrets but their own existence.
