The Demon's Beauty (Grym Hollow)

Isabelle would do anything for her sister—and she proved it. She will never regret seeking justice, even when fleeing her inevitable fate means accepting an unbreakable contract with Grym Hollow’s Guardian and becoming betrothed to the beastly Demon King in a loveless marriage.

Because that’s all it will ever be. She’ll make sure of it.

Oziel has seen three kings before him fall and then rise against their enemies with their wives—but he won’t succumb to their end mistakes. Pride is a demon’s specialty, though he knows when to pick his battles, and all his little human bride needs to do is break the terrible curse turning his subjects to stone.

But love is worse than any curse, with no place amongst depravity and sin, and the spitfire who waltzes right into his kingdom is making him feel something dangerous.

Not for long, though. The rules are set, guaranteeing their freedom once they’re safe. But with the magic dwindling—and a traitor in their midst—they’ll become the only other person they can trust…and the only one they can turn to once all hell breaks loose.

Book four in the Grym Hollow series. Each book follows one couple and ends in a happily-ever-after. The books can be read in any order, but reading in numerical order is best.
