Isabellae: Butterflies in the Mist (Isabellae #6)

On the sacred Hill of Tara, the children of Eire prepare to wage their final battle, this one against an army of powerful winged creatures claiming to serve the one true God. The remaining members of Isabellae's group are ready to die fighting at their friend's side, but additional help arrives in the most unexpected form, as the bloody conflict takes on epic proportions and the fate of all lies in its outcome. Themes of sacrifice, honor, and the true meaning of the way of the warrior come shining through in Book 6 of the series.
