Thirteen-year-old boy moves in with his guardian and begins to learn the skills needed to fight the centuries-old enemy of his (part-mortal) people. Finn has a temper, doesn’t like all the boring rules, and can’t understand why his guardian is SO strict. Which pretty much describes me at that age and explains why I could relate to this a lot more than the one time I tried one of the Twilight stories.
There’s also a nice plot turn near the end, when social services mistake bravely-earned battle scars for domestic abuse; I love it when the real world intrudes on a secret fantasy one. And it’s the reason I’ll be reading the sequel.
