I really loved the cover of Dominion. It was different and it reminded me of Disney classics (with a bit of a darker twist). I love Disney. So it was the cover that got me to read the book but the content that made me finish it. 
 I had trouble, at times, believing someone like Abigail would fall for someone like Gideon. To me he sounded like a supernatural version of Ted Bundy. An attractive and charismatic sociopath, who loved to kill. In contrast Abigail seemed really nice.
