Season of Crows: An Evershade Novel / Prix Gautney,

When a banished mousemaid and her crippled companion race across a field in the dark of night to warn Evershade of the impending crow attack, Ash and the other Walnut Keepers must choose to stay and fight for their beloved home--or flee for their very lives.

But how can a peaceful, weaponless society of woodland creatures ever hope to defeat the murderous crows? In the midst of the worst drought in Evershade history, Ash and the others must call on their talents and their allies in neighboring kingdoms if they are to have any hope of surviving the coming war.

And if they survive, what will they do when the water runs out for good?
