I found Dexter's willingness to cast Rita aside for someone who had more to offer in terms of wealth, beauty, and influence to be more accurate than Lindsay's usual depiction of a sociopath.

Normally cliffhangers bother me, but I just don't care about what happens to Dexter. Even when I'm reading the book, it's obvious that he's a fictional character. I'm rarely able to suspend my disbelief, these books are just a pleasant form of escapism.
