Wow...just wow. I agree with the few people that have had to wait to write a review due to "processing." Completely FLOORED here. 
 *edit* Ready to get into the review after catching some sleep. 
 I could go the spoiler route and post every single oh...my...god moment that I had a strong reaction to, but I won't. After all, most people like to read reviews BEFORE they read a book. 
 Did this final installment live up to the hype? Absolutely. Were all of my questions answered? Well...mostly. There were a few small things left open-ended, but much of that will be answered I'm sure in the spin-off series. 
 How can I convey the awesomeness that is the Fever series to anyone that's still unsure whether or not to read it? First off, I beg of you not to judge the first book too harshly because even though it's alright, you just don't understand the epic-ness of the Fever world until you keep reading on. This series really hits its stride at book 3, where it becomes like the book version of crack. 
 Let's go back to the tried and true checklist method that I will use to show how great Shadowfever is: 
 1. Strong main characters - check. Especially when you have a stubborn female and a strong willed male with secrets to hide 
 2. Good plot - check. I'd love to get inside this author's head and figure out how she came up with this very long, yet very ingenious story arc 
 3. Plot twists & turns - check. In spades. If you like trying to "solve" mysteries, then you will eat this series up 
 4. Satisfying, yet still "not quite perfect" ending - check. This is how a series should be wrapped up. It gave me what I wanted to have, yet didn't tie everything up in a neat little bow.
