Gregory Roarke — agent for the ultra-secret Icarus Group – has received a new assignment: locate a teleportation portal on a backwater colony world. But what should be a an easy assignment leads to a string of murders, and a race against an alien enemy.

Gregory Roarke–former bounty hunter, former Trailblazer, current agent for the ultra-secret Icarus Group–has received a new assignment: locate a suspected but as-yet undiscovered teleportation portal on the backwater colony world of Alainn.

The rival Patth are also searching for the device, and have considerably more resources at their disposal. Fortunately, Roarke has Selene and her incredibly sensitive Kadolian sense of smell. On paper, it should be a straightforward enough job.

But that was before there was a murder in the small town of Bilswift . . . and another one . . . and the discovery that the Patth are already on the scene and have narrowed the search to a heavily forested area in the hills and mountains east of town.

Most disturbing of all is the discovery that one of Selene’s people, a Kadolian teenaged boy named Tirano, is working at one of Bilswift’s fish markets. A boy who may have lost his parents before his proper socialization was completed. A boy who may be connected to both the murders and the Patth.

A boy who may be the potentially dangerous wild card that the Kadolians call changelings.
