Warning, there are spoilers in this review. This review is actually 2.5 stars.
First, let me tell the reader of this review that this book was very well on its way to having 4 stars, maybe even a 4.5. I loved the pacing of the book, and thought that up until the 80% mark, the story progressed pretty naturally. I liked the concept, and while Cassie seemed like she was more or less along for the ride, I was okay with it. The last 20% of the book nearly ruined it, and I thought that difficult to do.
For those who would like the plot of the book, Cassie is a 19 year old young woman in a story that starts in 1915, in Hermosa Beach, California. Four years prior, Cassie's father was struck with a terrible fever, and cured by a Dr. Gremhahn. Four years later, Dr. Gremhahn demands payment, and steals Cassie's younger brother Jimmy. For the rest of the book, Cassie and her mother, with the help of a magic "finder woman" named Diana, go on a journey to rescue Jimmy from Dr. Gremhahn.
About halfway through the book, Cassie is gifted a starfish pendant by Diana, who has agreed to train her in magic to help her against the gremhahn. This starfish is nearly never referenced in the rest of the novel, except for around 80% of the way through, when it suddenly becomes a Deus Ex Machina contraption. There is simply no lore behind the pendant, meaning that the fact that it does what it does makes no sense to the reader. One thing I may have given it a pass for was the way it shoots a beam of light to set fire to the gremhahn, killing it nearly instantly. That gives me throwbacks to sort of Hero Prevails stories like Sailor Moon, where the main character is as powerful as they need to be to kill the enemy in one shot.
This is where we get more of the weakness of the novel: the ending. For several chapters, Diana explains that to break the curses that the gremhahn brought upon each member of Cassie's family, it requires three people. Three. Distinct. People. In the penultimate chapter of this book, the starfish pendant suddenly gives Cassie all the power she needs to break the curses on everyone, including herself, something she was told more than three times that she needed three magically inclined people to help with. She describes it as reading words she had never read, as if they appear in her mind. This is the epitome of an easy out, narratively. I just feel that if the book was maybe 50, or even 30 pages longer, this may not have occured. Either that, or Razevich didn't know just how to tie everything in together (which is something I struggle with myself, as a writer).
The last chapter is another that screws with me. We know that Cassie gets her "Happily Ever After", and that Pax is now suddenly a selkie. Well, not suddenly. It's obvious throughout all of Pax's interactions that he's heavily connected to the ocean, even going so far as to say "the ocean is my home" when Cassie puts him under a binding truth spell temporarily. I, for one, had thought that this would mean that Pax was either the gremhahn in disguise or a servant of the gremhahn, so the fact that Pax is a selkie threw me for a loop.
One last thing that irked me about the novel was that Cassie didn't seem aggressive. She was very passive in her interactions, doing little more than changing her clothes to show that she'd actually done something for herself. Most, if not all, of her interactions are led by the other person. There's also the struggle with Cassie being practically unable to press people for information. If I were 19 again, and I were with a boy who said that the ocean was his home, without any indication of that being idiomatic or metaphorical, I would have at least said "What do you mean?", especially if he were under a truth spell that I had cast on him during that time!
Had that specific interaction gone differently, the entire final chapter of the book would have been pointless, or could have been changed to something that solidified the relationship between the two, with something besides "I'm a professor studying mythology and you're a mage". Honestly, there was little chemistry there. The only things we got about Pax was that he's a professor, and that he's attractive, and in the last chapter, we learn that he's a selkie. Other than Cassie being told in a vision that "the seals are [her] friend", there is practically no reason for the two of them to be as close and as intimate as they are.
All in all, I felt that there was just too little information given in the novel. The nuances of magic really just aren't there. It almost seems that there are no concrete rules, save for the fact that people either have magic or they don't. The romance is thrust in there, with little information about Pax as a person. I feel that these issues could have been eradicated, had the novel just been slightly longer and let the author work them out herself.
As an ending note, I would like to talk about what I felt Alexes Razevich did well in the novel. I loved the pacing, up until the final confrontation with the gremhahn. I loved how Cassie grows up, and how Razevich shows her growth in the clothes that Cassie is wearing. It's symbolic, and it's pretty effective... if the rest of the book lives up to that level of writing.
