To save her family from ruin, Elara agrees to a marriage pact with a man she's never met. But this is no ordinary union. Her fiancé, Lord Cassian Voron, is the heir to an ancient and powerful vampire clan, and the price of her family's salvation is her own blood. Bound by the Crimson Covenant, she becomes his personal blood source, a beautiful possession in a gilded cage. But Cassian is more than a monster, and Elara is more than a meal. In the glittering, treacherous world of vampire aristocracy, a spark of defiance could ignite a forbidden passion, or get them both killed.
