 In Midnight Frost we see Gwen really starting to come into her own; all of her hard work and training is finally paying off. She can now slay Reapers with the best of 'em and she's also quickly becoming the Pantheon's greatest defense in the looming Chaos War. The learning curve has been steep and unforgiving but Frost is finally proving herself worthy to be called Nike's Champion. In this installment we learn more about Gwen's dad's side of the family, a new character named Rory is introduced and our favourite Spartan gets a much needed wake-up call. But, as much as I love these books, the further along in this series I get the more predictable the story seems to become. This will in no way cause me to quit the Mythos Academy novels but I do wish that Estep would stray from her go-to format of Gwen gets attacked by Reapers in the library, kills them, investigates and then wraps-up with a new mission from Nike. 
 One of the things that I'm enjoying the most about this Young Adult series and that I don't usually come across in my typical reads is the quirkiness factor. What I mean by this is that Estep's able to get away with certain things that I'd otherwise normally roll my eyes at. Take Vic for example, I absolutely adore his snarky one-liners but if I'd come across a talking sword in one of my Urban Fantasy books I may have stopped reading then and there however, in this instance it totally works! Gwen has also become something of a celebrity on campus so the students invented an app to keep track of her whereabouts at the Academy; I thought the idea of a Frost tracker for my iPhone was one of the coolest things ever. Again, in adult fiction this would come across as creepy but in the Mythos world it's super cute. 
 I like how each installment features a different mythological creature; previously we learned about Black rocs, Fenrir Wolves and Nemean prowlers but this time around it's Gryphons that are front-and-center. Gwen seems to have a knack for making allies out of enemies and once again it pays off. I wouldn't be surprised to see Frost with her own little mythological army by the time the final battle rolls around. I really enjoyed comparing the North Carolina Mythos Academy to the one they visit in Colorado. At times it felt like they were two sides of the same coin; one evil and one good what with the two librarians and then of course, there's Rory. I thought that Miss Forsetti was a great addition to this series' lovable cast of characters and her nickname for Gwen is priceless! 
 Logan continues to be well... Logan. He's MIA for most of this novel because of what happened in Crimson Frost but Gwen does get the chance to voice her feelings where he is concerned and she's not nice about it either. I loved watching her put Mythos' best fighter in his place; sometimes the truth hurts! Hopefully this will be the last of their relationship woes. Towards the end, Frost gains an important weapon in the war against Loki and I think things will really begin to heat up in Killer Frost. As far as I know, Jennifer Estep is contracted for six books so the next installment may very well be the last. Even though this wasn't my favourite installment, Midnight Frost provided me with hours of great entertainment and really, that's good enough for me!
