Squirrel never expected to be anything other than a slave: the last animal slave in Bimmau. That is, until he is invited to a high profile wedding and takes a sip of the forbidden ceremonial wine, unlocking a mysterious riddle. The riddle reveals that there is a key which has the power to grant Squirrel his freedom (and a name ), but also could enslave anyone in Bimmau. Disastrous if it falls into the wrong hands Squirrel and his friends find themselves in a race to find Brittle's Key before the army of crows gets to him...and before the mysterious Colonel finds the key first.
