The Celaran Probe — Michael McCloskey

The Celaran Probe is the seventh book in the PIT series. Telisa Relachik studied to be a xenoarchaeologist at a time when humans had found alien artifacts but hadn't encountered live aliens. Rather than return to Earth with the modest spoils of the team's first Celaran expedition, Telisa decides to proceed to another Celaran colony site in an attempt to find living Celarans. New friends and enemies will be discovered beyond the frontier, while big surprises await the PIT team back home.
