The Heir & the Spare by Harper L. Woods

Once, I’d spent my life in the tunnels beneath the mountains. Now, I’m bound to a husband I didn’t want.

My mother waited centuries to find me on the other side of the Veil of Flesh and Bone where the Lunar Witches hid me. She sent her greatest weapon, the God of the Dead, when the Veil finally fell.

But I never expected to love his human mate, Estrella, the way I did–to feel the sisterly bond between us as if it had never been interrupted in our lifetimes spent apart since a rogue witch took her away.

But Mab sees love as a weakness, and she uses my bond with Estrella to manipulate me into a betrothal I never desired.

This marriage is a cage, a means of control that goes against everything within me.
But when Estrella is banished into Tartarus, I am left no choice but to journey to the Summer Court and take my place as a bride and a queen.

No matter what I leave behind.
