Kat Delaney is a world class caver and microbiologist. While investigating one of the deepest caves on Earth, she becomes trapped, along with her team of fellow cavers and scientists. Far below the ruins of a Mayan city, they struggle to escape this mysterious cave, reportedly cursed and haunted by the Lords of Death. Kat’s husband, Mark, a doctor and pioneer of nanotechnology with a deep-rooted fear of caves, must try to rescue her. He enlists the help of a Mayan guide, who turns out to have revolutionary ambitions.
Kat must keep her unravelling team together when they discover that something as threatening as the Lords of Death lurks within the cave. Mark must choose between trusting a guide who is patently untrustworthy, or leaving Kat to die. Will they escape? Will science be the solution? Or will it simply affirm their sentence as the Lords of Death win once again?
Sinkhole is a book that I can easily see turned into a movie. It has action, suspense, drama and real characters. Each one of the characters in the story had their own reasons for putting themselves in danger by exploring the caves. Their backstories are written with enough detail that you become engaged with them, even the "bad guys", but not so much as to go over-the-top.
The plot is very well done but I do have to say that the reason Mark goes after Kat is just a little to far fetched. That is the only reason why I didn't give the book 5 stars. It seems to me that Mark could have found someone to search for Kat if he would have kept looking but he took it upon himself to search for her even though he is deathly afraid of caves. It just seems to me that with his money and resources it would have been easy to send a search team in.
Overall I enjoyed Sinkhole as much as Ice Tomb (read my review) and look forward to reading more by Jackson.
I recommend this one for anyone who loves suspense thrillers with a sprinkling of sci-fi.
