For me, this was an easy decision, based on mostly on one factor: the quality of the writing. Both of these stories have incredible plot lines; they're actually similar in their paranormal aspects. However, The Dark Divine's writing just couldn't match up to Beautiful Creatures, which is filled with a Southern lilt that's almost impossible to top. Truly, both were fun reads, but I found Beautiful Creatures to be much more enjoyable to read (despite its length!)
I could probably go on for paragraphs and paragraphs, detailing character development and such, but I wanted to put this in a quick nutshell. Please head on over to The Shady Glade to read more about the book battle!
