Rudo finally gets to claim Ryker. All they want is their happily ever after, but their mating is threatened when Rudo's former alpha betrays them, sending Rudo back into captivity. Things only get worse after their rescue when the pack finds more labs, each worse than the last, the final lab leaving them exposed to a new, lethal virus that was created using shifter DNA.

Meanwhile, Enzo finds that his secret admirer is actually his mate, Heath, but a misunderstanding with some wolves leaves Heath traumatized. Now Enzo has to try to convince Heath that he isn't a monster, not an easy task when he has to take over the entire pack because his alpha and his team have been exposed to a weaponized virus. Tension is high, so how can Enzo possibly convince Heath to let him claim him?
