I haven't read the official published version, but I've read the Wattpad version, and honestly its AMAZING!!
The book takes you on an adventure and I constantly found myself saying, "Hadley is so strong, I wouldn't be able to do this."
The description is what pulled me in but the book itself is so worth reading, I finished it in a day because I was so hooked!
I recommend it to everyone, and if you can't buy the book then just read it on Wattpad.
