Aquila

Description
Aquila is a dark-grey raven who first appeared in Cornelius' Curse.

Cornelius' Curse
In Cornelius' Curse, she was buried by an avalanche while trying to capture Shadow and Cornelius. The two SkyTalons believed she was dead, and Shadow grieved for her.

Can someone put the name of the book that Aquila survived in here?
Despite the events of Cornelius' Curse, it was proven that Aquila was alive, and she went back to the Raven Tribe, redeemed herself, defeated Malik in a fight, became the leader of the Raven Tribe, and appointed Arric as her new deputy.
