This is no book for kids, I'll say that. Leviathan reminds me of a James Patterson novel - the adult kind. It's full of unnecessary swear words (even the infamous F-Word) that drags it down a point for me. The dialogue doesn't fair much better, being rather bland, though Senator Lee is usually quite funny. There is little in the way of character development, Captain Heirthall and Colonel Collins being the exceptions. That aside, the book is rather well-written and quite powerful at certain points. The ending was rather suspenseful, as was the cliffhanger endings. The Leviathan is well-described and the background behind its captain and crew was interesting. However, the author seems to assume that everyone knows every little piece of a boat, and I most certainly didn't. "Uh, where's the stern again?" Most characters were rather bland to me, the aforementioned Collins and Heithall, as well as Virginia, Lee, and Farbeaux, being exceptions, as they had personalities. The use of names was rather confusing as Colonel Jack Collins could be Colonel one minute, Jack the next, and so on. I really enjoyed reading this book despite its many faults. I'd recommend it to anyone who enjoys suspenseful novels, fictional books about ships, or people who read the previous three books in the series.
