Simon R. Green gives a series of small hints to those familiar with his amazing book "Blue Moon Rising". In his one-eyed, scar-faced hero, there are several clues that this could be Rupert, with Fisher bearing a distinct likeness to Julia. It is very intriguing, and he would never dream of slipping enough to tell you for sure. The Hawk & Fisher books stand on their own, with dashing tales of love, honor, betrayal, evil, vengence and a distinctly darker tone than Blue Moon Rising. There is not as much humor in the characters, but if you liked Rupert and Julia in the other book, you will love Hawk and Fisher in these.
