I didn’t go in expecting a lot... and I guess that’s good. Jameson still annoys me. Avery’s security team is a joke even though it’s emphasized many times how tight her security is. There’s no substantial character development, all the side characters are very 2D. Grayson might as well be part of that cast. 
The only reason this isn’t a one star is because for the first 3/4 of this book I was enjoying the mystery. Then the family tree got way too twisted and there was a twist within a twist that didn’t impress me.
