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.

With the safety of their loved ones in the balance, the risks they must take may cost them everything. 

An accident. A forfeit of freedom. A descent into danger.

Liobhan, the young warrior and bard, has lost her brother to the Otherworld. Even more determined to gain a place as an elite fighter, she returns to Swan Island to continue her training. But Liobhan is devastated when her comrade Dau is injured and loses his sight in their final display bout. Blamed by Dau's family for the accident, she agrees to go to his home, Oakhill, as a bond servant for one year.

But Oakhill is a place of dark secrets. The menacing and enigmatic Crow Folk still threaten both worlds and while Brocc battles them in the Otherworld, Dau must battle his own demon - despair.

When Liobhan and Dau begin to expose the evil at the core of Oakhill, they place themselves in mortal danger. For their enemy wields great power and will stop at nothing to get his way. It will take all the skills of a Swan Island warrior and a touch of the uncanny to give them any hope of survival . . .
