This series started out with some promise even though I didn't find Tristan to be that likeable of a character at first. However, this second book was a struggle to get through and I most likely won't read the third, unless it's to skim through quickly to get the gist of the story. 
 The Savage Blue was in dire need of editing. Whole chapters and chunks could have been cut out of the book to make the storyline faster paced. There were just bizarre things thrown in (some random card game?) and overall, I just lost interest in exactly what Tristan was doing by the end of it. 
 The premise of this series was interesting - despite the abundance of YA mermaid novels right now, I haven't come across one with a male main character, even if his narrative voice does not strike me as authentically male. I think the author just plain lost her way and ultimately could have done much better with input from several editors. The idea was there and was developing fine in the first book, the execution was just a total mess after that.
