The Deathless One Book Summary From Goodreads
A princess murdered at the altar makes a deal with the god of death for vengeance and to save her people in this first in a unique romantasy trilogy from USA TODAY bestselling author Emma Hamm.
Jessamine was raised to be a leader for her people, but when the land is overrun by an incurable plague, she must enter a political marriage to save them all. A union that should have brought hope only brings death as her new husband murders her at the wedding altar and seizes the throne.
But her death is just the beginning. Her spirit is met by the Deathless One, a god of death yearning to return to the mortal plane, and he needs her help. The two of them make a deal—her life and the return of her kingdom in exchange for his resurrection. But the Deathless One is a known trickster, and a deal with him is one made in blood.
Jessamine knows the Deathless One is a dangerous ally, but the longer they work together, the more she wants him and the less she can stay away. As their connection deepens, soon she wonders if she even wants this contract to end. Perhaps the more appealing throne is the one by his side, but she’d have to turn her back on her people to get it.

My Thoughts on The Deathless One
I’m about 3 chapters into reading this book. Personally for me it’s not an easy read. The writing is beautiful, but it’s hard to read a lot in one sitting. I’ve put it down and I’ll attempt to read it again later.
Stay tuned for an update.
