I got Return to The Isle of The Lost by Melissa De La Cruz, so now I'm reading the first book called Isle of The Lost by her as well. I haven't read it/finished it yet, but when I do... I'll read the sequel too. :P
For anyone wondering, it's based on the Descendants movie from Disney Channel. At first, I was against the movie... but when I watched it, I loved it. Mostly, because it had Dove Cameron. ^^ There's supposed to be a sequel to it coming up too, and it's already been confirmed by her and other sources.
