I really don't know how I should review this book. I loved the first 3 books in this series but this 4th & final book in this series did nothing for me. At times I found it boring where I was just skimming the pages. The parts in the book that were supposed to be the the 'high' parts of the book totally fell short. There were some cute parts of the book like how Ethan communicated with Lena from the Otherworld. I also liked how Ethan got to see his mom again in the Otherworld & that he got to spend some time with her. Other than that thought this book was severely lacking excitement for me. 
 This book should've taken me at the most 3 days to read but it took me a week. I found myself not wanting to pick it up to read & when I did finally pick it up I procrastinated reading it. You may be asking 'why did you continue reading if you didn't enjoy it that much?' My answer to that is because I invested a few years with this series from when Beautiful Creatures came out & I wanted to see what happens with Lena & Ethan and the Gaitlin/Caster clan! 
 I'll still recommend this book because as a whole I really did love the Beautiful Creatures series!
