I really liked Crimson Waters. Unlike recent DL titles, the ended didn't seem rushed, and I hope Ricky can stay for at least a couple novels, perhaps looking for his sister?
Besides the awesome action scenes, such as Jak and the armor cat, Ryan's terrific fight with Tiburon, etc, there was also a great deal of character , something we don't really see all that often in these novels. All in all, this book made me happy and had all the action, pulp and character that I've come to associate with the series.
