Mercenary Partners Dhulyn Wolfshead and Parno Lionsmane have been assigned the task of escorting the Princess of Arderon to her wedding with the new Tarkin of Menoin. But they soon learn that the Mercenary Brotherhood has a second job for them - a secret mission to find out what happened to two Brothers who were sent on assignment to Menoin a year ago, and who have disappeared. Once in Menoin they discover that their old friends Gundaron and Mar-eMar, there as Scholars investigating old Caid ruins, suspect that the disappearance of the Mercenary Brothers is linked to a series of bizarre, ritualistic killings. When the Princess of Arderon's corpse is found, mutilated in the same way as the others, Dhulyn and Parno track the killer into the Path of the Sun, an ancient labyrinth from which people rarely return. But Mercenaries are not ordinary people, and Dhulyn and Parno draw on their skills to reach the heart of the Path. What they find there is the entrance to another world, a world in which Red Horseman - Dhulyn's nomad people - have not been wiped out, a world in which the Marked - whether Finder, Mender, Healer, or Seer - are hunted down and killed as "broken" Can Dhulyn and Parno locate their missing Brothers, identify and stop the killer, and find their way back through the Path of the Sun before Dhulyn's own Mark qualifies her for execution?"--Back cover.
