Two years ago, Nikolai Volkov and Luke Fontenot nearly destroyed each other in a playoff series that ended with an ugly hit and words in the handshake line that neither can take back. Now they're wearing the same jersey for the Atlanta Firebirds, and their captains expect them to play nice. They can't even be in the same room without the temperature dropping ten degrees. Then the team cat has kittens — bonded siblings who scream when separated — and somehow Volkov and Fontenot each end up with one. Same building. Shared elevator. Mandatory kitten visitation schedules. Co-parenting with the man you hate most in professional hockey wasn't in anyone's contract, but neither was discovering that the person who drives you out of your mind on the ice might be the only one who makes sense off it.
