Welcome to my website!
Emperors of the Ice is now available both in the original hardback (with four maps and over 70 photographs) and as an e-book. It won both an 'Outstanding Book' designation from the National Science Teachers Association and a Washington State Book Award; reviewers have described it as "an enthralling tale," and "so gripping you will not want to put it down." You should probably stop reading this, click on the link, and buy copies for all your friends, right now.
You Are Here: A User's Guide to the Universe is a short tourist guide to absolutely everything. It's now available both as a paperback and as an e-book.
The Fire Seekers (Book One of the Babel Trilogy) will be published by Skyscape in November 2014. No cover yet - I'll post one when we have one. It's a thriller about the origin of civilization, the meaning of life, and who's trying to wipe us out, among other things. It will seriously mess with your head.
I'm also working on several other books.
