Read the Summary

From USA bestselling author K.M. Moronova comes a delicious arranged-marriage romantasy.

In a world ravaged by war and ruled by vengeful gods, love is both a weapon and a curse…

Haunted by her role in a massacre that reignited an ancient war, demigod knight Alira is cursed to relive her kingdom's destruction―dying again and again at the hands of the Blood Knight, a ruthless demon commander. But when the demons propose a peace marriage to end the bloodshed, Alira volunteers herself, desperate to break the cycle and save her people.

Betrothed to her enemy―who is also the lost demon boy she once tried to save―Alira must navigate a dangerous path between vengeance and forgiveness. Kalel Lornhelm, haunted by his own dark past and the monstrous hunger within him, is torn between hatred and a growing, forbidden attraction.

As assassins close in, gods interfere, and the threat of betrayal hangs over their union, Alira and Kalel are forced to confront their intertwined destinies and the curse that binds them. Can their love bring peace to Faultore, or will it doom them all?

Stories That Show Up When Kids Need Them Most

💛 More Than Just a Bookstore

When you shop at Flirting With Fiction, you’re doing more than buying a book—you’re helping us deliver hope.

A portion of every sale goes directly to Fun With Fiction, our nonprofit that brings the power of story to children facing trauma, loss, or major life changes. Through our Book Buddy program, we create hand-picked book packages tailored to each child’s age, interests, and unique situation.

It’s not just a box of books. It’s a message that says: you matter, you are not alone, and your story is still being written.
