Bittersweet Christmas

Orphan Liam Ryan isn't asking for much this Christmas—just his Uncle John. And he's counting on Father Christmas to find a way to make that happen.
But when Father Christmas tosses Liam's letter, claiming that the kid is asking the impossible, his daughter, Winter, takes over. Half-pixie, Winter, longs to do something important with her life, starting with getting a job at the Order of the Shadow Accords, the organization that polices the supernatural world. When she discovers Liam's uncle works for the Order, it seems like fate.
Savaged by werewolves and bitten by a vampire, no one knows what to expect of John Ryan, but it won't be anything good. So there's no way he's getting involved with his nephew...or anyone else. Worse, he's getting a babysitter over the holidays. But when he meets irrepressible Winter, all that matters is whether she likes her guys to be naughty or nice....
The Order series is best enjoyed in order.
