"Lakewalker Barr Foxbrush returns from two years of patrolling the bitter wilds of Luthlia against the enigmatic, destructive entities called malices, only to find that the secret daughter he'd left behind in the hinterland of Oleana has disappeared from her home after a terrible accusation. The search for her will call on more of Barr's mind and heart than just his mage powers, as he tries to balance his mistakes of the past and his most personal duties to the future."--Provided by publisher
