BOOK- ON DEADLY GROUND- A desperate sister 
Museum director Kate Fontaine made two promises to her dying father—protect her ne’er-do-well brother and return a stolen statuette of the Maya god of earthquakes to its temple. But when her brother is kidnapped and the price to save him is the priceless artifact, keeping one promise means breaking the other. In a no-win situation and facing a dangerous trek through the jungle, Kate is forced to rely on a guide she doesn’t trust… yet whose touch makes her yearn for so much more. 
A cynical guide 
The only person Max Rivera can truly count on is himself. That's why he prefers to work alone. Unfortunately his Devlin Security Force assignment to guide and protect Kate includes covertly finding proof her kidnapped brother has sold black-market antiquities. And sticking close to this delectable and vulnerable woman proves more dangerous to Max than all the threats in the jungle. 
A race against time 
While following the kidnapper’s instructions, Max and Kate must outrun black-market smugglers and a predicted earthquake in a race that takes them from Washington to England and into the Costa Verde jungle. But as perilous as their quest becomes, when desire flares between them, risking their lives seems simple next to risking their hearts.

What an action packed story.  The villains that are after them just kept on coming; ruthless, desperate and a boatload in number.  Don't let that scare you away though, because it wasn't done in a confusing way.  There were so many but they are connected and made sense to the story.  Greed and power just caused them to swarm.  What Max and Kate went through, was quite the ordeal.  Even when Kate wasn't sure she could trust Max, it was still really fun to see how well they worked together.   I enjoyed it when they were in the middle of a "hopeless" situation and Kate was able to help pull something together; at times helping to rescue Max.  Nice touch.  She was terrified but thinking of her brother needing help pushed her beyond what she thought she could do. She was tougher than she thought.    I thought the author did a good job describing the areas Kate and Max had to go to. The Mayan culture and beliefs as part of the story added a lot.  Do I know if is accurate? No, but I enjoyed it.  The struggle that Kate and Max went through; not to do anything about their attraction was good too.   I liked both of the M.C.'s and liked how we were able to see how certain things drove each one of them.  Kate's need to be organized and control things and Max's need to avoid rejection you could really feel.  I thought both were done well and you could understand it.   For some reason, I felt more for Max, maybe because he was so strong, a warrior but the rejection he dealt with in his life really came across.  
There were a couple of love scenes in the story, that weren't over the top.  
Some people may need to know that in one part of the story, in a village there are implied rapes. I know some people can't handle that; implied or detailed.  That is the only reason I mentioned it here. 

I received a free copy of this book in exchange for an honest review.
