After one explosive night together, eagle shapeshifters Cael and Randall know Sidonie Lanier is their breedmate. Despite her being the daughter of their greatest enemy.

Instead they seduce her and discover she is their human breedmate, the only woman who will satisfy them. The sex between them is like none any of them have known before, and they can't get enough of each other.
