Halt, Will, and Horace set out for Hibernia, where a quasi-religious group, the Outsiders, is sowing confusion and sedition, and they find that secrets from Halt's past may hold the key to restoring order before the last kingdom is undermined.

When a cult springs up in neighboring Clonmel, promising to quell the recent attacks by lawless marauders, people flock from all over to offer gold in exchange for protection. But Halt is all too familiar with this particular group, and he knows they have a less than charitable agenda. Secrets will be unveiled and battles fought to the death as Will and Horace help Halt in ridding the land of a dangerous enemy. Perfect for fans of J.R.R. Tolkiens Lord of the Rings, T.H. Whites The Sword in the Stone, Christopher Paolinis Eragon series, and George R. R. Martins Game of Thrones/A Song of Ice and Fire series.
