I've really been enjoying the Mythos Academy series and Midnight Frost is another great installment.  This book pretty much picks up right after Crimson Frost as Gwen is struggling with the events at the end of that book (trying not to give away any plot here).  While there is a nice recap of events, this series really needs to be read in order to get the full effect.

So that said, my biggest gripe about this series is that we're in book 5 and over the course of these five books, about 4ish months have elapsed.  In these four months, Gwen has learned about this mythological world and finds out she's being hunter by Reapers.  She's become Nike's Champion, accidentally helped release Loki.  And she's gone from being the weakest person at the school to actually being able to fend off Reapers (albeit still not as good as her friends and classmates).  I guess what I'm saying that a whole lot is happening in these 4 months and it seems a bit exaggerated.  I can't imagine Gwen being that good, that fast.  However, if you set aside the timeline, it's nice to see her growth and not being quite so foolhardy and annoying.

I loved the trip to another of the Mythos schools, this one in Colorado.  The introduction of yet another character, Rory, and I can't wait to see how she figures in to the final book. I'm glad that Gwen is finally holding her own in battles, and boy where there a couple of great fight scenes.  Gwen's friendships are strengthening and we're still kinda in the dark when it comes to Logan.  And oh my goodness, the gryphons! 

I can't wait to see how this series ends and have already picked up book 6.  Well done, Ms. Estep!
