Bests & Worsts Reviews from Amazon

I love Kate Morton's previous novels and didn't want them to end. So when this one came out, I began reading it as soon as I could. But I am not enjoying it like I should, like I did the others. I am so lost and so disappointed. I get who Elodie is and her set of characters, and Edward and most of his set of characters, but who the heck is Leonard and Jack? And somebody new I ran into last night, they just sort of appear out of nowhere and I don't know who, where or when they are. I need somebody who understands this book, if there is someone like that, or the author herself nearby to answer my questions! Maybe I just need to start over and take notes, if that will help, or just give up. Maybe a reader's guide to each chapter. Gosh, reading one of my favorite authors shouldn't be this hard!
