So you are the first person to find a lost island full of dinosaurs. Who do you run to with your discovery?
A) The National Geographic Society.
B) The U.N. (or at least a friendly government)
C) The Chinese mafia.
If you answered C, then you're a main character in Cryptozoica.
I just finished this 2010 novel by Mark Ellis, having stumbled on it on Amazon the other day. It a fun little diversion; a modern-day lost world tale intentionally mimicking the unabashedly macho pulp you used to find in the magazine section of your local grocery/drug store. (Hence the Mack Bolan reference in my post title.) The author comes from that background, having created and written most of the post-apocalyptic Outlanders series.
Cryptozoica is well-crafted but flawed. The author tries too hard to channel Dan Brown, so there is a plot involving a hidden manuscript of Charles Darwin, secret societies and Ancient Alien-like conspiracy theories. There's also the far-fetched premise that the main characters, upon discovering the island, convince the Asian mob to fund turning the isle into a Jurassic Park-like resort. And, being a dinosaur nerd myself, the author makes a lot of annoying little mistakes about his dinosaurians -- such at getting the number of fingers wrong on one of his main monsters.
Still, I enjoyed the novel, especially since there are are so few books of this type published anymore. And as a bonus, it comes with some nice black-and-white illustrations by one of the main artists for the Hollow Earth Expedition series of roleplaying games. You can currently buy a digital copy for $3 USD on Amazon, so you haven't spent much money if you don't like it. (Not sure if it is on Nook or in other digital formats.)
