Boundary by Ryk E. Spoor and Eric Flint

Science Fiction

What do you do when you find what looks like an alien fossil on the K-T Boundary? That was the problem that confronted Helen Sutter on a dig that also had the strange fossil surrounded by several dinosaur fossils. As the story unfolds that fossil leads to even stranger events and Helen winds up on Mars!!!

A lot happens between these two events. Boundary has science, action, adventure, great characters and relationships all in an exciting format. I re-read Boundary because Threshold, a sequel, is coming out in June. The stage is set of more action and adventure and I am looking forward to Threshold.

Baen published Boundary by Ryk E. Spoor and Eric Flint in 2006.
