While I felt this book was frustrating to get into because of the switching perspectives and tightly held secrets, the ending has to be the most gratifying of any mystery book I've read, and was one I could not have predicted. I do think that the characters were well written, they had distinct personalities and motivations for the choices they made and why they grew to feel ashamed or enraged by them. Yet I often have little patience for stories that unravel slowly, so I found myself not appreciating the book until I got to the ending. Ultimately, I would recommend The Guest List to others looking for a moody, twisty mystery story and I look forward to reading Foley's other titles.
