This book is from a series of books in the (Amish of Summer Grove) this is number two in that group. You don't have to read the first book in the series, as the reader is brought up to speed pretty quickly. The first book does really flesh out all of the characters and the fun part of this series is that for the most part of the two books so far, they aren't really as much about Amish characters as they are about how they are brought up and their belief system which is challenged when Ariana and Skyler find they are switched at birth, Ariana has to go live with her natural family or the father will sue the woman involved in the switch accident, and so she agrees to live as an English person for a year.
Her sister or the girl who was brought up as her for all of those years has gotten into drugs and she really doesn't want to take part in the switch back, but she has a choice go live with her natural Amish parents or go to a rehabilitation center to get her drug problem under control. Boy do these girls run into problems living as they never have before!! Ariana has to leave behind a boyfriend/ soon to be fiance and the cafe she bought to run.
I was given this book in exchange for a fair review which is what I have done above through the publisher WaterBrook Multnomah. The following is the description of this book as found here on Good Reads.
"Family, community, faith, and love. These "quilt blocks" sewn together made Ariana's beautiful life. When they are pulled to pieces, will anything familiar remain? The Old Order Amish life Ariana Brenneman loved vanished virtually overnight with the discovery that she was switched at birth twenty years ago. Now she's immersed in the Englischer world, getting to know her mother, and under the authority of her biological father, an atheist intellectual with resolute plans to expand Ariana's worldview. Only Quill Schlabach, a childhood friend living Englisch, can help steady Ariana's tilting ground between the two worlds, but can she trust him after so many betrayals? At the same time, Skylar Nash is forced to choose rehab or spend several months with her true relatives, the large Brenneman family and their seemingly backward life--no electricity, no technology, no fun. What the young woman can't leave behind is her addiction to illegal prescription drugs and deep emptiness from the belief that she doesn't belong in either family. New ties are binding Ariana and Skylar to the lives they were meant to have. Can they pray for the wisdom and strength they'll need to follow God's threads into unexpected futures? Fraying at the Edge is the second novel in The Amish of Summer Grove series"
