We have had the best time writing our first Young Adult novel, set 20,000 years ago, at the height of the Pleistocene Ice Age.  What fun to writer about American lions, sabertooth cats, dire wolves, giant bison, mammoths and giant beavers.  Had Mike on tenterhooks (your word for the day) when young Lynx fell into the crevasse.  It’s great inspiration to be able to watch bison out the window while writing about their ancestors who roamed the continent twenty centuries ago.
