As the youngest of seven brothers born with magical gifts, Jack’s often felt he has something to prove. But revealing their powers makes them targets of the fae, who will stop at nothing to hide their existence from mankind.

When Jack gets dragged through a portal and winds up in Faerie, he finds an ancient relic he simply can’t leave behind. But escaping from Faerie is only the beginning as the harp’s former owner is determined to see Jack pay for his crime.
With old enemies returned new enemies awaken, revealing the Sorleys aren’t the only family in Straifield with ties to the fae.
