I was really hoping to like this book but it just fell flat. I never got any connection to any characters and any attempt by the author just seemed overly forced. An example of this is the main character (written in first person) tells you in two different paragraphs how much he loves his wife but never really shows it when she is around.
Every that happens in this book is also so nonchalant. Yeah two people have been bitten and maimed on separate dives but they never think or talk about not going in the water and just continue on like it was no big deal. Hey we've seen some ghost but no biggie. And when all the weird stuff happens and the crap hits the fan the characters never react in a realistic way and they just seem to go about their regular business. There is also a weird ghost sub-plot that did not need to be in the book at all.
Another little thing that bothered me was at the beginning of the book the author thanked someone for their input on deep sea diving and said how much it helped the book but the book only takes place under water for about 5 pages if that.
For a book named Deeper this book just wasn't deep enough for me to really get into it.
