 KILLER FROST has everything you could possibly want in a series finale; from the suspenseful build-up, to the end all battle, to every character's HEA. I loved how Jennifer Estep concluded MYTHOS ACADEMY, and I'm positive that fellow fans of Gwen Frost will agree. 
 This installment is beautifully paced with just the right amount of pages allotted to the story set-up, final showdown, and tying up loose ends. I expected the last fight between Gwen, the pantheon, the reapers and Loki to be epic, and Estep certainly delivered. She took her time detailing every kick, swing, and dodge which transformed this novel's closing chapters into a live action brawl that unfolded inside my head. I loved that Gwen put everything she has learned about the artifacts from working at the Library of Antiquities to good use to help her defeat the trickster god; it added meaning to her journey thus far and established clear links to all of the previous books. 
 Estep ensures that every character, secondary and main alike, has a role to play in this series conclusion. Logan, Daphne, Carson, Oliver, Alexie, Metis, Nickamedes, Grandma Frost, Rory, Rachel, Nyx, and Vic... they are all by Gwen's side fighting the good fight. I liked how practically every protagonist got their own version of a HEA; except for Rory--do I sense a possible spin-off in the future? For several installments now, I've been speculating about who Raven really is, and what's the purpose of the stone statues, and this novel answers those questions too. I was blown away by the completeness of this story; I don't think Jennifer Estep missed a single thing! 
 Gwen doesn't have it easy in KILLER FROST; she's overly paranoid about reaper attacks, and has the weight of the world on her shoulders thanks to the added pressure of knowing that she's the one who's supposed to kill Loki. Then her grandmother gets kidnapped, and she's forced to choose between one life and many. Even though the ending may give you heart failure, I have to hand it to Gwen because she really does give it her all and proves herself worthy of being called Nike's champion. Frost is no longer "that weird Gypsy girl everyone at school loves to gossip about" but a bona fide heroine who should be proud of how far she's come, and hold her head up high. 
 I will miss Gwen Frost and her crew of misfits, but as a reader, I couldn't be more satisfied with this series finale. Thank you Jennifer Estep for dotting all your i's and crossing all your t's; KILLER FROST is a masterpiece and I can't wait to see where your writing is going to take you next.
