Storm Glass follows Opal Cowan (who some may recall from Snyder's Study series). Opal is a "one trick wonder" with glass magic, and quite honestly spends most of her time moping around The Keep. Until she is enlisted to help a nearby clan with some troubles they've been having. Soon, Opal's world is turned upside down as her magic takes new twists, mulitple people keep trying to kidnap her, and, worst of all, some boys show interest in her. 
 Not going to lie, I really enjoyed this. The plot does have a sort of unbelievabe inter-connectedness but it somehow works, even when setting up scenes that seem like they shouldn't occur. There were some interesting twists, especially in the bad guys, that I felt worked well. 
 At first, Opal's character felt incredibly whiny and hard on herself. Luckily, I wasn't the only one who noticed that as other characters told her to gain some confidence. As the story progresses Opal does get better in that way; there are still times though when you want to grab her by the shoulders and shake her. For other characters, I found Develen intriguing and was interested in what angles he was working; Ulrick felt like he could've been fleshed out just a bit more (hopefully in the next books of the series). 
 Snyder's writing is lovely. The great thing about Sitia is its landscape, which she describes wonderfully through the many journeys the characters take. I also really enjoyed how she was able to give information on characters (age, eyes, hair, clothing, etc.) without feeling like they were being listed, or read off like chapter two of a Baby-Sitter's Club book. 
 However, I did feel like the events of Fire Study were brought up too often. That's not to say the ones that directly involved Opal and affected how her character would evolve since then, but moreso the ones where she just bragged up everything Yelena did ever. Hopefully that decreases in the next set. Though Yelena's involvement in this one made sense and was nice to see. 
 All in all, definitely good. Already started the next in the series. 4.73/5
