I was very confused at who became who and who Aunt Judy was. If she was one of the twins then Judy and May would not have met each other for such a bond to be there. The book begins with someone asking Avery if she was Fern. I would have liked it better if Grandma Judy was Fern. Or I am I missing something?
This answer contains spoilers… (view spoiler)[Grandma Judy was really one of the twins born to Queenie right before the rest of the children were taken. Trent Turner Jr found Judy and Lark and reunited them with May when they were all young adults (shortly after they had gotten married, I believe). I was confused too since some of the children had different names. I think two other people asked about this on here, you may want to read those answers as well. (hide spoiler)]
