Adrian sat on the railing and watched Lindsay go through an elaborate and unwittingly sexy calisthenics routine. “I don’t know, but I suspect my blood has something to do with it. Much like Fallen blood conveys a temporary immunity.”

“Other vamps have bitten Sentinels before. They weren’t then able to practice yoga on an uncovered deck.”

“But only Lindsay has drunk Sentinel blood exclusively after being turned by one of the Fallen. Every cell in her body is nourished by blood that protects her. As long as she continues to drink from me, she might keep the benefits.”

“A minion with the gifts of the Fallen.” Damien lifted a hand to his brow, as if pained. “If Sentinel blood cures the vampire disease and imparts immunity to the healthy, and others were to learn of this?—”

“—we’d be hunted to extinction. I know.”

“Without the lycans, we’re sitting ducks.”

“Siobhán is testing whether lycan blood is an alternative since they were once seraphim, too.”

Damien was silent for a moment. “I’ll pray for a miracle.”

“Pray for us all.” Adrian set his hands on the railing and tipped his face up to the sun. The morning breeze blew across his feathers in a soft greeting. “We’re going to need it.”
