Potboiler and very forgettable one at that. The Dirk Pitt guy is unrealistic and not even likeable. Too much of detailed description about seafaring stuff, and not all that grippingly written.
I mean sure most potboilers are not realistic, but I expect either fast paced action, not reams of boring description, or wry humour, or likable characters.
Yawn. off to Manto next.
