There is just too much sexual tension between them for this trip to be comfortable. Rick and Kates decide to hire our hero, Ben, as a guide through the Amazon rainforest.Right off the bat, Jillian and Ben do not get along. Rick enlists the sketchy Kates to help fund the exploration in exchange for some of the lost treasure. Unfortunately, she makes the mistake of informing her brother Rick, who only fantasizes of finding lost treasure. Determined to clear her father's name, Jillian heads south to Brazil to find the Anzar.

Much to her amazement, she finds in his journals that the civilization did in fact exist and that her father had coded a map on how to find it. After being turned down for a major archeological gig, Jillian decides to read her father's meticulous notes on the myth of the lost Anzar civilization. As an archaeologist, most people in the industry only see her as 'Crackpot Sherwood's' daughter, due to her father's fascination with myths, particularly that of the Amazon. Jillian Sherwood's career has hit a major roadblock. If you are at all offended by ’raunchy jokes’ this may not be funny to you. While I say it is fun and funny, it is sexual humor, some of it is on the graphic side (for lack of better wording). Definitely a different way to play out a “moment” like that. While Ben is brash and blunt from the get go, the “moment” of realization is not just expected but also kind of fun. As the characters progress through the story as well as through the jungle, they become better and better. The angst between Rick and Jillian was strong. The sexual frustration and flirtation between Ben and Jillian is at times fun or even funny. I really enjoyed the combination of action, adventure, mystery, humor and romance. Knowing that there was something not right, Ben made Jillian’s protection his prime mission, second only to finding out what Rick and his low-life friends were up to. As a guide in the Amazon, Ben Lewis took pride at being able to size up any situation quickly and finding out that a woman would be part of his next job, left a bad taste in his mouth.

Keeping several key pieces of information to herself made sure she would be useful till they found the city.

While Rick was the one that finally acquired the funds and got the expedition started, the animosity that he felt for her was always there leaving Jillian concerned about how things would end. Finding the money and the people to help her to locate the lost Stone City in the middle of the Amazon jungle would eventually show the world that her father was not the crackpot that everyone thought he was.

Being an archeologist, just like dad, Jillian had a special insight in decoding the notes and the maps that she had found. Wanting to remind herself of the man that was her father, Jillian Sherwood convinced her brother (Rick) to let her finally see some of their fathers notebooks.
