The Grimm Hacker (Grimm Society‪)‬

When Everly Hart's best friend Holland disappears, all signs point to an online game orchestrated by the enigmatic Mad Hacker, a grimm who preys on unsuspecting Gravemark students. He lures them into his perilous games, where victory promises rewards but defeat could lead to a descent into madness.

Everly is torn between her complicated relationship with Hunter and her growing feelings for half-werewolf Ian. Both men are dangerous distractions as she tracks down the latest killer grimm plaguing their town.

With her friend's life on the line, Everly is forced to navigate the treacherous depths of the dark web and engage in the Mad Hacker's deadly games. The clock is ticking, and if Everly can't solve both mysteries soon, someone she loves could end up either mad or dead.
