SPOILERSMagic Strikes (Kate Daniels, Book 3)
by Ilona Andrews
This series is really really growing on me even though this particular book revolves around the tired gladiator/fight to the death arena event! Kate's friend gets himself in trouble by trying to steal tickets to a super secret arena event called the Midnight Games in order to keep him from getting busted by the Pack, Kate agrees to attend the event with a God. While there he asks her to investigate one of the teams who appear human but have supernatural abilities beyond what they should be capable of. Chaos, as usual, ensues.
