Perfect for you if...

You love enemies-to-lovers with actual chemistry and banter, especially when one party is absolutely bewildered by affection.
You enjoy paranormal romance that doesn't take itself seriously but still delivers genuine heat and emotional stakes.
You're drawn to found family and redemption arcs where a hardened character learns to soften without losing their edge.

Maybe not for you if...

You prefer your demons genuinely menacing throughout, with no humour or vulnerability in the mix.
You're looking for slow-burn romance. This moves fast once the curse breaks, and the cat-to-human transition happens partway through.
You want a standalone. This is part of the Hotter than Hell series, so you'll want to continue with the world and characters.

About this book

Morax, a Duke of Hell, is cursed into the body of an oversized black cat with horns and useless wings. Now living as a pampered pet with a veterinarian named Finn, his threats are perceived as adorable and his rage met with treats and belly rubs—reactions he secretly doesn't entirely dislike. Finn's relentless kindness blinds him to every hint of darkness Morax projects. No matter how Morax plots or glares, Finn sees only a creature needing love. When Finn's goodness eventually breaks the curse and Morax's true power returns, the dynamic shifts. Free and formidable once more, Morax intends to claim the mortal who saved him. However, seducing Finn proves more complicated than wielding demonic power. Winning over this stubborn human requires grand gestures, a touch of terror, and a heart that has grown genuinely fond of purring at his side.
