The Sum of its Parts Series by E.M. Holloway

When a young woman is found murdered on the property she used to own, her brother enlists Puck Schneider - the nosiest teenager in Arcadia Lake - to help him find out who killed her. It doesn't take Puck long to realize that he's getting way more than he bargained for, as he's drawn into a world of werewolves, monsters, and murder.

With things in Arcadia Lake finally settling down, Puck begins to think about expanding his pack. Then he gets the news that the hunter community is determined to get Hugo Durand out of jail. Fortunately for Puck, someone else seems just as determined to keep him there. Unfortunately, his mysterious ally doesn't seem to care if Puck and his pack are caught in the crossfire.

Things in Arcadia Lake take a turn for the complicated when the Lycan Tribunal shows up to evaluate Puck as an alpha. Not only are they dubious that a human can truly hold that mantle, their leader holds a grudge against Connor Henley. If Puck fails the trial, the sentence is execution - and if the pack objects to the ruling, their lives are forfeit as well.
