Thrill Ride is the fourth book in the Black Knights series by Julie Ann Walker. It is a solid addition to the series featuring Rock and Vanessa. Rock has a burn notice put out on him and he goes into hiding to protect himself while he tries to find evidence to prove his innocence. The Black Knights are determined to find and help him and Vanessa does. The crap pretty much hits the fan once Vanessa meets up with Rock and they find themselves running for their lives through the jungle. It's an intense and exciting beginning to this thrill ride of a book. 
 I enjoyed Thrill Ride. Rock is an interesting character and it is nice to learn more about him. The mystery is a unique and interesting one. Vanessa is a likable character as well, though she was rather emotional. I think she was channeling a sprinkler through parts of the story... For a character that claimed to rarely cry it was a bit unexpected. 
 Overall, Thrill Ride is very well done and I recommend it to fans of the Black Knight Series and fans of Romantic Suspense. I look forward to more books by Julie Ann Walker.
