The 6th Extinction

ONE LAST HISTORICAL NOTE

I hope you enjoyed this book. It’s the tenth novel in the Sigma series, debuting on the tenth anniversary of the first (Sandstorm, 2004). Knowing that milestone was upon us, I thought I’d use this opportunity to tease a bit to the past. Like seeing the return of Ashley Carter and Ben Brust, those stalwart Antarctic explorers, who along with Jason, found themselves in much trouble in my very first novel, Subterranean. Additionally, in this new book, I also wanted to acknowledge what’s to come, with some big changes hinted at in these same pages — because Sigma’s greatest and boldest adventures are still on the horizon.

So I hope to see you out there!
