When the truth about the blood oath is revealed, Calla has a devastating choice to make: leave the vampires she's caught feelings for or stay and fight for the life she's built with them. And each choice has severe, irreversible consequences.
With the hunters at large, carrying out attacks of their own, and a betrayal by someone close to Calla, she remains stuck in a whirlwind of fear and confusion. Not to mention the darkness still lurking in Kade or the psychotic vampire Selene lurking in the shadows.
Faced with a life-altering ultimatum, Calla must choose to give up everything she has come to know or the future she is terrified to want.
Fated in Ruby is the fourth installment in the bloody, sexy, reverse harem Blood Oath series!
