John Charming, Knight Templar and werewolf, and his girlfriend, the Valkyrie Sig, find their camping trip interrupted when John's goddaughter is kidnapped. Constance, like John, has both Knight and werewolf blood, and is key to a treaty between the two groups. Both share the responsibility of guarding her, and both think the traitor is in the other's ranks. John isn't a big fan of working within any ranks at all.
I've long enjoyed the amount of mythology that is worked into the Pax Arcana series. This is what John Charming does, he's almost a century old, and he knows the territory. I'm also struck by his believability as an almost century old (regenerating, Wolverine-style). Yes, he's still a smartass after all these years. He's been through some stuff; he was raised by people who thought he should have been killed as a freak of nature, and he's seen someone he loved killed because of him. He has very believable problems with authority. But as odd as it is, he also has a certain maturity. His relationship with Sig is one of the most reasonable I've seen in urban fantasy. They didn't rush into it after some stuff that went down with her previous relationship in the first book, and when their various issues get in the way they work stuff through and deal with it like adults.
I love this series. It and the Rivers of London books by Ben Aaronovitch are my two go-to recommendations for fans of The Dresden Files. I just wish I knew what the release date was for the next book, Legend Has It.
Overall: A
