Luckily (for me) it wasn't too paranormal nor too erotic, but plenty of psycho and thriller
The paranormal bit was that the protagonist visits a "half-way land" to say goodbye to his recently deceased wife. This didn't seem out of place, it seemed like a nice thought about the interim afterlife. There wasn't a lot of sex, just some encounters that mostly moved the story along. I didn't particularly like the character of the psychiatric consultant, she seemed a bit unprofessional.
This seemed a long book. It wasn't "un-put-downable" but I kept going back to it to see what happened next. It's not a masterpiece by any means, but certainly an enjoyable read with some good ideas and plots.
I will probably check out some more books by David Callinan.
