Thicker Than Water

Outcast operative in the Supernatural Investigation & Crime Bureau (SICB) Callen Blackheath finds himself doing what he does best: defying orders and giving his boss a headache in the thick of an operation he shouldn't be in. And there's no way he's walking away, not when the investigation has become deadly personal.
Needing to protect the only family member he has left, this wolf shifter will do whatever it takes to stop the blood farms and destroy the dangerous drugs the vampires will kill for. But he doesn't expect Liam "Thatch" Thatcher, the head of a special task force team, to receive a bite that pulls him into the centre of Callen's world.
Bonded by memories and blood, together they navigate the operation that has wider reaches than they could ever imagine. And when it comes to matters of the heart, Callen knows in order to win, he needs to risk it all.
