Every so often you just need to get away from it all and read a no-holds-barred, action-oriented, good guy vs bad guy action story. This one fits the bill to a tee.
I have read three other books by Rollins so far and to tell the truth I was starting to get a little worried. The plots seemed to be getting a bit thin (or unrealistic) and the characters a little cliched. But Deep Fathom was a pleasant switch even though it is one of his earlier novels. It kept me turning pages and I cared about the characters. The ending was a bit over the top perhaps and some may consider it to be a cop out by the author (I can't really explain without a spoiler) but my feeling is if you're reading this kind of action novel then you'll be in the right frame of mind for the ending anyway. And you will definitely be satisfied.
