I've read all of Gleason's other books--romance and vampires--and of them all, this is my favorite.
Although I'm a big romance reader and generally read that genre most often, I really enjoyed this unique, fast-paced adventure novel. It's very different from anything else I've read by Colleen Gleason, yet it still has her flair for description, characterization, and the action scenes she's done so well in her Gardella books.
This story is well-written with not only a fast, complicated plot, but it's also got something most action adventure novels and movies don't: character development. I can't wait to see what she does with the next one in the series! Marina Alexander is a fascinating lead character (a good foil for Dirk Pitt, if you read Cussler's books), and one I hope we see more of. And the supporting cast, each with their own weaknesses, faults and backstory, were interesting and compelling.
The whole idea of geo-terrorists trying to protect our earth from the rape of humans is both frightening and sad. This is a situation where I can relate to the villain's perspective, while at the same time, abhor them for the way they go about trying to get attention.
Although there are aspects of the book that border on far-fetched, that's pretty much the norm for these types of stories--I've come to expect it from Cussler, Clancy, and Dan Brown. But that's the fun of these thrillers.
Overall, this is a thrilling, action-packed book with a thoughtful premise and I hope to see more like this from Gleason, along with her other stories.
