Dominion (Book 4 in the Serenity Series)
by Marissa Farrar
Since meeting Serenity eight years ago, vampire Sebastian’s whole existence has been about protecting his family. When an unexpected question causes a rift between the couple, Sebastian finds himself with a dead body and no recollection of killing him. With Sebastian's strength failing and after everything they’d been through, Sebastian never imagined he’d be the one who’d need saving.
