I'm having a hard time rating this one, so I'm going to leave it in the middle. I will say that I have enjoyed this duology, it is a fun time full of adventure and drama and if I don't think too hard about it, I don't have any issues. I love all our characters, main, side, and even the villains here. The first half of the book was definitely the best.
I really think this book should have gotten a couple more proof reads and edits. While I am able to look past these things, some were so incredibly jarring. Like mixing up character names! Oliver is kissing Inu? Oliver locked up with Sebastian? You mean Oscar? OOF. That was a pretty big whoopsie for me that I couldn't really shake. Also some parts a new line would start in the middle of a sentence, obviously by accident, and some time later in the book, the first few sentences of a new chapter were formatted up in The Mysterious Deep excerpts, or the excerpt was weirdly double/triple spaced leaving room for only about a sentence or two of the actual chapter... while this is not why I have rated this only 3 stars, it does lead me to believe that this was perhaps rushed out too soon.
So lets get into the nitty gritty....
Spoilers ahead...
I am disappointed by the "quickness" of everything. It is always "we need to go here and do this thing" and then suddenly we are there and it takes about five for it to all be over and done with. I also felt like we had sooo much build up to Rose being so special with ties to these mythical beasts, and we never really get to see the extent of that. I mean, Im glad that we were told what it was? kinda? The extent of her "gift" is an angry cat who loves her, a grumpy crab who tags along for the last couple chapters, and Koinu helping them steer clear of the witches and lifting her up from the depths (both instances were a sentence really), and that is it. There was so much build up for sweet Koinu and I was just left pretty disappointed.
Inu and Val. I was..... underwhelmed, and that really pissed me off. I absolutely loved these characters, but it all happened so fast. I also wanted DESPERATELY for Inu and Rose to have a relationship that we got to see on the page. All the truce we got between them was in Roses POV where she says "we've come to an understanding and are better now" (barely paraphrasing here) and so when everything happens I found it to be... forced? I don't know, I just feel some type a way about it. Val hurt more, but even then we never really got to SEE their relationship we are always just TOLD about it. Kit changed a lot of that, so I was happy to see more of her character.
I think all in all, it is a good and fun time, if I don't think too far into things.
