Boundary Publisher's Summary

Paradigms Shift, Worlds Collide!

A daring and resourceful paleontologist uncovers something at the infamous K-T boundary marking the end of dinosaurs in the fossil record - something big, dangerous, and absolutely, categorically impossible. It's a find that will catapult her to the Martian moon Phobos, then down to the crater-pocked desert of the Red Planet itself. For this mild-mannered fossil hunter may just have become Earth's first practicing xenobiologist!

A new hard SF thriller from best-selling alternate history master Eric Flint and ace game designer Ryk E. Spoor.

    When the strange fossil she'd discovered ended up giving her a trip to Mars, Helen Sutter thought she'd gone about as far as any paleontologist would ever go in her lifetime. But when you've also married A.J. Baker, overconfident super-sensor expert for the only private agency in space (the Ares Corporation), and your best friend Madeline Fathom Buckley is a former secret agent who's just signed on as the chief of security for the newly created and already embattled Interplanetary Research Institute of the United Nations, there's always somewhere farther to go.

    Sergeant Samuel Morgan Campbell had been in plenty of tight spots before, but nothing like this. It had happened in a few terrifying seconds: the starship he and his crew travelled on, the Outward Initiative, shattered to pieces before their eyes and disappeared, leaving them stranded in the endless night of deep space on Lifeboat LS-88 - all systems dead, light-years from any known colony.
