Bound to the Demon Duke

Bound to the Demon Duke is a gothic romance set in a mysterious English castle haunted by an ancient supernatural pact. Emrys Lovell, a brilliant paleographer fascinated by forbidden manuscripts, is invited to Mornwraith Castle by the reclusive Corvus Fenwick, known throughout England as the "Demon Duke."Inside the castle, Emrys discovers a terrifying family secret: for centuries, the firstborn sons of the Fenwick family have been magically bound to the Hollow King, a supernatural entity that steals their reflections and slowly feeds upon them.
Corvus has survived the curse for fifteen years, but his time is running out. As Emrys investigates the castle's forbidden library, cryptic marginalia, an ancient grimoire, and a mysterious mirror, he discovers that the curse may have a loophole. According to Tamsin Fenwick, the only way to break the pact is through genuine love freely given-by someone who sees the bound duke completely, including his darkness and supernatural burden, and chooses to love him anyway.
What begins as a scholarly investigation gradually becomes a dangerous emotional bond between Emrys and Corvus. Together, they must uncover the truth hidden inside the living Grimoire before the Hollow King claims Corvus forever.
