Maerad is a slave in a desperate and unforgiving settlement, taken there as a child after her family is destroyed in war. She is unaware that she possesses a powerful gift, one that marks her as a member of the School of Pellinor.

It is only when she is discovered by Cadvan, one of the great Bards of Lirigon, that her true heritage and extraordinary destiny unfold. Now she and her new teacher must survive a journey through a time and place where the forces they battle stem from the deepest recesses of otherworldly terror.

Maerad is a girl with a tragic and bitter past, but her powers grow stronger by the day. Now she and her mentor, Cadvan, hunted by both the Light and the Dark, must unravel the Riddle of the Treesong before their fractured kingdom erupts in chaos.

The quest leads Maerad over terrifying seas and vast stretches of glacial wilderness, ever closer to the seductive Winterking -- ally of her most powerful enemy, the Nameless One. Trapped in the Winterking's icy realm, Maerad must confront what she has suspected all along: that she is the greatest riddle of all.

The young heroine’s brother discovers his own hidden gift — and the role he must play in battling the Dark. Hem is a weary orphan whose struggle for survival ends when he is reunited with his lost sister, Maerad. But Maerad has a destiny to fulfill, and Hem is sent to the golden city of Turbansk, where he learns the ways of the Bards and befriends a mysterious white crow.

When the forces of the Dark threaten, Hem flees with his protector, Saliman, and an orphan girl named Zelika to join the Light’s resistance forces. It is there that Hem has a vision and learns that he, too, has a part to play in Maerad’s quest to solve the Riddle of the Treesong.

In an increasingly battle-ravaged land, Maerad, Cadvan, and Hem desperately search for one another as they make their separate journeys. The Black Army is advancing north, and even as Maerad faces a mighty confrontation with the Landrost to save Innail, all of the Seven Kingdoms are threatened with bitter and devastating defeat.

Yet in Maerad and Hem lives the secret to the mysterious Singing, and legend holds that if they release the music of Elidhu together, they have the power to defeat the Nameless One. Can brother and sister find each other in time to fight this all-powerful enemy, and are they strong enough -- even reunited -- to defeat him before all is lost?
