 Dark Frost is hands down the darkest installment I've read so far in this series; it kicks off with a bloody Reaper massacre at the museum and only escalates from there. There's no happily-ever-after to be had in this Mythos Academy book, instead things go from bad to worse and if you're a fan of this series then you know that that means Loki, the god of chaos, is probably involved. Even the feel good side story featuring Gwen's friend Nott, the Fenrir wolf from Kiss of Frost, has a bittersweet ending to it. There was however, some development on the Logan front and I for one can't wait to tune in to their first date in Crimson Frost! 
 Jennifer Estep pulled a fast one on me with the main plot of this novel; all signs pointed to the most likely suspect so of course, I immediately discounted this character as the possible big bad. But, then I began to doubt myself as I neared the end of the book and no other prospects had surfaced so, I started to believe in Estep's original villain. Well, I'm sure you all know how that turned out. I was blindsided by the real perp who I'd previously pegged as a possible future addition to Gwen's circle of friends. That's what I get for assuming that because this novel is shelved as Young Adult that the plot line must be simple. I really don't give YA authors enough credit sometimes. 
 I was surprised by how quickly things escalated in this installment. The first two were about Frost growing into her powers and coming to terms with the fact that Norse, Greek and Native America gods alike not only exist but are at war with Loki. The Mythos Academy main story arc really takes the lead in this book which basically means that... the sh*t has hit the fan! Some of the things that happen in this novel are downright shocking; I found myself thinking "Estep did NOT just do that!" on more than one occasion. Buckle your seat belts folks because this third installment is one heck of a bumpy ride! 
 I enjoyed how action-packed this book was and I loved that Estep wasn't afraid to spill a little blood; this installment reminded me a bit of her more violent Elemental Assassin series. I'm happy that Logan and Gwen finally worked out their differences and can move forward with their relationship. I understand the need for slower romance in YA but I do need at least two kisses per novel. Minimum! Dark Frost is just what the title promises: dark. This is no children's bedtime story.
