At the notorious Silver Chalice Inn, Rowan Faelan, a fae trickster infamous for slipping away from unpaid debts, finds his luck at an end. When the barkeep invokes a tavern curse, the next soul through the door becomes bound to Rowan's endless tab.

That soul is Maribel Hayes, a weary ice witch seeking only a night's rest. Instead, she is shackled by glowing runes to a fae she despises on sight. Furious, but unable to break the curse, Maribel is forced to accompany Rowan across the Monster Realm to settle his debts—each owed not in coin, but in dangerous bargains with vampires, banshees, and necromancers.

Together they cross haunted lands, their reluctant partnership tested by peril and bound tighter with every act of survival. Yet as Maribel unravels the truth, she discovers Rowan's debts were never mere mischief: he carries an eternal bargain that no one has ever dared to share.

Now she must choose—walk away and let the Realm claim his soul, or embrace the bond forged in fire and frost, binding her fate to his forever.
