book #6: Fablehaven: Keys to the Demon Prison by: Brandon Mull
So, this is when everything comes together. It's the end of the Fablehaven Series, and everything has been leading up to the ending of this book. It's crazy sauce what happens, andit makes perfect sense. I don't think it really needs a summary, as you wouldn't read this book without having read all four of the other books. So hopefully you've made it this far! As always, I recommend this book!
