A Vow Made In Blood: Crowns of Tenebris

By Millie St Graves

Princess Zora Starborne is heir to Tenebris, a vampire kingdom carved from ice and shadow. To secure peace, she must wed Athalan Bloodgrim, crown prince of a rival realm. But before their vows, Zora must survive the brutal wedding rites of Tenebris; dangerous trials meant to prove a bride's worth.

As betrayal seeps through the court and enemies gather in the dark, Zora faces more than politics and war. Athalan is a mystery she cannot ignore, and Riven-her fey ex-lover turned queen's guard-will stop at nothing to reclaim her.

Torn between love, duty, and survival, Zora must decide whether to embrace the crown's demands or carve her own fate. In Tenebris, where blood is power and desire can kill, every choice comes with a price.

Book one in the Crowns of Tenebris trilogy.

Perfect for fans of Sarah J Maas, Carissa Broadbent, and more.
