At twelve years old, Ruby Calvino is the youngest human player in the Tooth & Claw championships – a legendary contest where Wolves battle Reds in a vicious game of “What’s the Time, Mr Wolf?”. It’s her fast legs and even faster mind that leaves her as the last player standing during the championship final, and she’s ready to claim victory. But when the undefeated Alarick— the wolf player hunting her— is finally upon her, he…drops dead?

With poison found in Ruby’s bag, all fingers (and paws!) point to her. Desperate to prove her innocence, she teams up with Fillan, a young wolf accused of helping her commit the crime. But figuring out who killed Alarick certainly won’t be easy while on the run from cops and a vicious wolf assassin.

Luckily, Ruby’s Tooth & Claw training just might come in handy!
