Caught between barren wastes and the expansive ocean, the four Alliance colonies have had to fight tooth and claw to defend their lush territory from scavengers and rogue magicians for generations. By holding fast to their traditions, these brave and noble cats have created a fragile peace for themselves that is uprooted when two rangers from Marsh Colony are found dead under mysterious circumstances.
The entire Alliance is shaken-especially Spottedshadow, a Mentor from Field Colony, and Dawnfrost, an Envoy poised to take leadership of Oak Colony. These two young mollies are determined to discover who, or what, killed the rangers, and stop it before it can kill again. Together with friends and allies from across the territory, they will embark on a mission to save their homes and lives from a danger none of them could have imagined.
However, not all threats lurk outside the Alliance, and facing this foe will force all the colonies to tear out the roots of their own prejudices and beliefs.
