The backcover blurb does a good job of conveying both the general plot and the tone of the book: a ballsy auditor brings down governments by exposing widespread corruption and has to hide from--well, from everybody--until after the first trials log in his testimony. No place on earth is safe, so he joins the small scientific community 50 million years in the past at Eocene Station, the one place governments and assassins can't reach him. Only, things aren't quite what they seem there, either, and the arrival of a big name auditor is not entirely welcome.
Although 'Cannon' Ball is a fun hero, his wife Tempest is the most interesting character, written with Duncan's trademark wry humour. A totally sexual being in a highly repressed puritanical future, she is the embodiment of every sex goddess ever. Sex, violence, and prehistoric monsters--what more could you want? (Full disclosure--I was the editor on this novel).
