The characters are one-sided; the plot's motivation just doesn't work; but it is all very exciting nonsense.
This audiobook sounds like one big pat on the back by the author to himself. The plot is ridiculous, telegraphed from a mile away, and is full of product name drops, like Pitt's car collection and brand names of dive equipment. The dive science is flawed and the dialogue is littered with almost non-sequiter corny one liners, accentuated by Scott Brick's smarmy intonation. German, Irish, and hispanic characters all sound like toffee-nosed snobs, talking down to everyone. I truly hope the rest of Cussler's writing is not this bad.
