Eighteen-year-old Liobhan is a powerful singer and an expert whistle player. Her brother has a voice to melt the hardest heart, and is a rare talent on the harp. But Liobhan's burning ambition is to join the elite warrior band on Swan Island. She and her brother train there to compete for places, and find themselves joining a mission while still candidates. Their unusual blend of skills makes them ideal for this particular job, which requires going undercover as traveling minstrels. For Swan Island trains both warriors and spies.
Their mission: to find and retrieve a precious harp, an ancient symbol of kingship, which has gone missing. If the instrument is not played at the upcoming coronation, the candidate will not be accepted and the kingdom will be thrown into disarray. Faced with plotting courtiers and tight-lipped druids, an insightful storyteller, and a boorish Crown Prince, Liobhan soon realizes an Otherworld power may be meddling in the affairs of the kingdom. When ambition clashes with conscience, Liobhan must make a bold decision—and the consequences may break her heart.
The young warrior and bard Liobhan 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 Dau's home as a bond servant for the span of one year.
There, she soon learns that Oakhill is a place of dark secrets. The vicious Crow Folk still threaten both worlds. And Dau, battling the demon of despair, is not an easy man to help.
When Liobhan and Dau start to expose the rot at the center of Oakhill, they place themselves in deadly 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 a hope of survival. . . .
Bard and fighter Liobhan is always ready for a challenge. So when news arrives at Swan Island that the prince of Dalriada has gone missing after an assault by both masked men and the sinister Crow Folk, she's eager to act.
While Liobhan and her fellow Swan Island warriors seek answers to the prince's disappearance, the bard Brocc, Liobhan's brother, finds himself in dire trouble. His attempts to communicate with the Crow Folk have led him down a perilous path. When Liobhan and her comrades are sent to the rescue, it becomes clear the two missions are connected--and a great mystery unfolds.
What brought the Crow Folk to Erin? And who seeks to use them in an unscrupulous bid for power? As Liobhan and Brocc investigate, it will take all their strength and will to continue pursuing the truth. With the safety of their loved ones in the balance, the risks they must take may cost them everything.
