Two warriors. One wields the power of music, one the strength of her sword. Both face a grave threat in this enthralling historical fantasy.

After a violent encounter with masked men and the sinister Crow Folk, Prince Aolu of Dalriada disappears without a trace, and his companion Galen is seriously injured.

Liobhan and the Swan Island warriors seek answers to the prince's abduction. For Liobhan this mission is personal, as Galen is her beloved brother.

While she and her team investigate, Liobhan's younger brother Brocc is in serious trouble. Brocc's secret attempt to communicate with the Crow Folk triggers a shocking incident, and sends him on a path which endangers the one he loves above all else.

What brought the Crow Folk to Erin? And who plots to use them in an unscrupulous bid for power? As Liobhan and Brocc seek the truth, it becomes clear the two missions are connected - and an extraordinary mystery unfolds.
