It's springtime - hundreds of Crows set out on their yearly migration and converge at the Gathering Tree. This sacred Gathering is an opportunity for the six crow Clans of the Family Kinaar to assemble, to make decisions and to celebrate being together.

But when young blood is lost, sacred laws are tested as an illegal Mob seeks revenge, and a schism threatens the unity of the flock. The Family's situation is made yet more precarious when a severe blizzard hits and the Crows are faced with the dilemma of where to find shelter. Breaking age-old decrees and working together may offer their only chance of survival ...

Here is a startling view of the world from a bird's-eye perspective, complete with its own set of beliefs, mythologies and politics. But it's a world familiar to us too - where the needs of the individual often clash with those of the group, and where the desire to be free must be tempered with the need to be safe, to survive.
