From Publishers Weekly: Weis (the Dragonlance series, etc.) returns to her Stars of the Guardians series (The Lost King, etc.), this time collaborating with military expert and first-time author Perrin, formerly of the Canadian Defense Department. Cyborg Xris and the six other members of his mercenary Mag Force 7 team are back as well, seeking to foil a plot to assassinate the galactic ruler, King Starfire. High-tech combat and violent death permeate the narrative, which initially focuses on Xris's mission to do away with his former colleague, the transsexual Darin Cowan/Darlene Mohini. Xris, who was once wholly human, believes that Cowan betrayed him, leading to the accident that left the Force ruler imprisoned in a cyborg body. When a foppish, drug-using member of the team is kidnapped during that mission, the Force discovers the plot by the Knights of the Black Earth to kill the king. Adventures and misadventures, leavened with plot twists, humor and ample quotes from Sun Tzu, follow. Unexpectedly subtle yet filled with fast-paced action, this above-average space opera will please Weis's many fans.

From Library Journal:
The cyborg warrior Xris and his team of professional mercenaries seek out an elusive target whose past betrayals warrant speedy execution; their plans change abruptly, however, when they uncover a plot to destroy the galaxy's young king, the last living bearer of the Blood Royal. Set in the same universe as Weis's "Star of the Guardians" series, this effort by the popular sf/fantasy author and first-timer Perrin is a fast-paced galactic adventure designed to introduce the motley crew of antiheroes known as the Mag Force 7. Spiced with humor and a dash of romance, this space opera should appeal to most fans of sf adventure.
