Dr. Sofia Pierce has recently mated with the infamous vampire Gage Gallegos, known as Lucifer. Just as they think their lives are finally perfect, a shocking revelation shatters their peace: Sofia isn’t who they thought she was.
 
Not even close.
 
Sofia’s true nature is unlike anything the vampires and hybrids of The Alliance have ever encountered. As her mysterious past begins to unravel, Sofia discovers her entire life has been a carefully constructed lie. Terrified by the truth, she fears confiding in Gage, worried it could tear them apart.
 
Zander, the leader of The Alliance, announces to the warriors that Sofia is not human and now falls under their protection. More disturbingly, he reveals that the killer Vega, whom they've been relentlessly tracking, is specifically targeting Sofia. To ensure her safety, Zander assigns round-the-clock protection to Sofia and all their mates, recognizing that if Sofia is in danger, they all are.
 
Sixteen of the most formidable warriors from Gage’s and Ambrose’s teams surround Sofia, forming an unbreakable shield of protection. As time passes, Sofia’s humor, resilience, and warmth endear her to each of them, creating deep bonds. They would die for her.
 
To further ensure Sofia’s safety, The Alliance begins building her own blood army. Warriors who receive her blood will be bound to her, able to sense her distress and locate her through their blood link. They will serve her, protect her, and stand ready to face any threat.
 
As Sofia grapples with her new identity and the growing danger around her, she must navigate a path filled with peril and uncertainty. With Gage by her side and an army at her command, Sofia prepares for a fight that will test the limits of their love and the strength of their bond.
 
But something goes terribly wrong.
 
Now Sofia and Gage must either figure out how to deal with this mistake or let it destroy them. If that happens, then everything they have fought for will be for nothing.
