Jen Hewitt, a quiet geology graduate student, doesn't actually believe in time travel. Were it possible, rocks from the age of dinosaurs should already be cluttered with artifacts from future time-tourists. Nevertheless, she proves with fellow geologist Jonathan Renner that a human skeleton encased in Pleistocene rock came from their own time. Their work, coupled with fundamental research by physicist Susan Arasmith, reveals an unexpected character to the universe that carries them from the safe world of science into a struggle with powers and possibilities they hadn't imagined. The three friends, along with Kar-Tur, a frightening mystic from the ancient past, learn that discovery is sometimes as much about faith as knowledge, and that friendship and love are often found where least expected.

As a huge fan of all things science fiction, I was super excited to read this book, and it did not disappoint! For me, this book had all the goodies a sci-fi fan would want. Right out of the gate I loved the premise of the book. A geologist finds a modern human skeleton in 40,000-year-old rock?! Sign me up!
Not only does this book have a superb premise, but the characters are fleshed out as well. I loved how the chapters jump from person to person, giving the reader insights into their lives and thoughts.
This story moves quickly as well, which is always something I enjoy. I may not have understood all of the science terms or language, but Colson explains the experients and concepts in a way that an average Joe could understand and appreciate.
Fans of sci-fi, speculative and just plain adventure will love this book. Time travel, government conspiracies, and romance are just the tip of the iceberg with this book.
