Query: Please tell me the other Robin Cook books are better!

This was the first and probably last Robin Cook novel for me. I was disappointed after hearing so many positive comments on his medical thrillers. The "fantasy world under the sea" science fiction in this book lacked several components, including plausibility and interesting dialogue. Many comic book heros have more dimensions than the stock, predictable characters in this novel. A plot twist in the last pages is the only original idea in the otherwise stale material.
