Well, after reading this book, it's no wonder Kowalski loves his explosives! I've read all the Sigma Force novels to date, and then finally picked up Ice Hunt to get some idea what happened before all the rest.... Wow! What a wild ride! Very wild indeed. The grendels are enough to give a girl nightmares. It always amazes me how fabulously Rollins ties together real archaeology & paleontology, history, social and science news, and gives a killer story from the lot.
