This was a much slower paced book than Guardian. There was not a lot of nail-biting action that keeps you wanting to forego everything else and just read but everything seems to be an integral part of the storyline. The relationships between the characters was more fully developed. I was glad to see the relationship between Hannah and her biological father did not suffer when she found out the truth. Hannah had many of her questions answered when she went with the mermaids and spoke with (no you don't get the spoiler). The answers will hopefully make her life much simpler, at least in the relationship area. This was a good addition to the series and I can't wait for the next one. I'm still waiting to hear about Gabriel's life in the 300 years before he was reunited with Hannah.
