Avery and Chloe grew up carrying the same loss and the same promise, and that bond leads them into the ancient vampire House Vale together. When they leave years later, they leave as one. Even with husbands who command castles, estates, blood vaults, and the Night Court, nothing can drag the sisters back. Through moonlit pursuits, scandalous whispers, and fragile reconciliations, all four discover a deeper truth: family is built not by bloodline or title, but by loyalty chosen from the heart.
