The Bloodbound Knight by Megan O'Russell

Some vows are made to be broken.

With a hoard of forbidden knowledge on their side, Jerek’s crew holds the fate of the feu in their hands. But the line between victim and villain is thin, and the enemy they face will push them to the brink of darkness.

A heart will be broken.
A love will be tested.
An ally will betray them all.

Vengeance and salvation are now within reach. Will victory be worth the cost?
