Redeemed by Moonblood: The Alpha's Cursed Bride

Elena, sole heir to Moonblood, is betrayed by her stepmother and half-sister and offered as a sacrifice to Logan, Blackpeak's Alpha, who is cursed to destroy anyone he loves. Her blood unexpectedly calms his madness, and their contract leads them to defeat family enemies, pack traitors, and a corrupt priestess before confronting the awakened vampire progenitor Dracula. Elena sacrifices her divinity to destroy him and wanders the human world without memory. Logan searches for three years and finds her in a Seattle flower shop, courts her again, helps restore her memory, and joins her in eliminating the remaining vampires before their marriage.
