I will say that Constantine's writing style is lovely and rather poetic. Too bad she waste it trying to be the next Anne Rice or something.
I first read this book over summer break when I was bored out of my mind and decided to go to the library. I saw this on the shelf and immediately became interested. I absolutely couldn't put it down because I wanted to understand the characters and find out what happened. I was very unsatisfied with the ending of the book, but then I found out about the sequel. The ending was not an ending, but a setup for the next novel. It worked for me. I bought the other two books as soon as I found them.
The darkness and sexuality of Sea Dragon Heir is not for everyone and I can see where it would turn people away from this book. I loved the characters and the air of mystery shrouded about them. They were so... human. There isn't a Mary Sue or Marty Stew in sight in this story. I never once regretted buying this book.
There is a great piece of work in there somewhere, the world and setting are wonderful the characters just are horribly lacking.
