Telisa Relachik studied to be a xenoarchaeologist at a time when humans had found alien artifacts but hadn't encountered live aliens. After a harrowing brush with a real Trilisk on Chigran Callnir Four, the PIT team, fresh with four new members, heads out on a new type of expedition: hunting a live Trilisk.

Telisa can’t imagine more deadly creature to pursue, but she’s determined to stop the representative of an elder race she’s come to see as a threat to Earth, even an Earth run by her enemies.

The Trilisk Hunt is the fourth book in the PIT series.
