Query: Disappointing Cussler -- tell me it ain't so, Clive

First Cussler novel I've ever given up on (half-way through). Hadn't been able to stop turning the pages of any of his previous efforts (and I've read them all), but this one was just too scattered/disjointed and had too little character development. Sadly disappointing.
