Trying times in Oxford Mississippi in 1933
Format: Kindle
The Calamity Club features a cast of strong women and several weak men. The official charitable women are not charitable and the unofficial ones are courageous and are filled with good will. Stockett weaves a long tale of poverty, desperation, determination and sisterly love. Only two sets of sisters are blood related but those who are not, bond by working together for a common purpose.
Stockett serves up humor and pathos in equal measure with a dash or two of realism. Her character development makes The Calamity Club well worth reading
Like The Help, a screenplay should be forthcoming.

So Good!
Format: Hardcover
Some parts of this are reminiscent of The Help, but it is a brand new story. Even though it appears to be a LONG book (650 pages), it goes fast and is hard to put down. The story takes place in Mississippi in the 1930's. 24 year old Birdie travels to see her married sister in Oxford for the purpose of getting some financial help for her family. Her sister Frances married into a seemingly wealthy family, which for reasons that soon become clear, has now fallen on hard times. Eleven year old Meg lives in an orphanage and is treated badly by the volunteers that staff it. If her mom isn't going to come back and get her, then she wants to be adopted as soon as possible, but most people want babies, not older children. Charlie turns up at the house where Birdie is staying with her sister's family. She's bright and helpful, but what's her real story? How are they all connected? This story is at times hilarious and at other times heartbreaking. It has its share of villains, but most of the characters are likeable and you want them to succeed. Just HOW they succeed is the heart of the book, and I won't tell you and spoil the surprise. This is well worth reading, though, and I strongly recommend it.

Outstanding book
Format: Kindle
I loved this book so much that I'm sad that I've finished it. The story is fascinating, the characters well developed and the themes were important and heart wrenching. This is definitely one of the best books I ever read. I can't summarize the story without spoilers and I would not want to deny you the opportunity to enjoy the unfolding of this beautiful story. This is a book I will not forget and I look forward to Kathryn Society's next wonderful book. She is a tremendous author. Thank you Kathryn for the gift of this book!

Worth the Wait
Format: Kindle
Kathryn Stockett's The Calamity Club is well worth the wait, just as good or even better than The Help. This historical novel has all the literary ingredients to be added to the classics. This book is both engaging and horrifying since it reveals the cruel beliefs in Mississippi's past and explains the rigid mind-set of contemporary politics and culture. I was incensed by the ignorance and lack of empathy. However, as throughout history, the theme of women helping other women gave the story conflict, suspense, and lots of humor. The characters and plot are so engaging I would like a follow-up story, maybe a part two. I am ready for a movie version, if Meg and Birdie are well cast. The Calamity Club was worth the wait!

Entertaining
Format: Kindle
I read this book on Kindle in about 3 days. Birdie Calhoun, one of the main narrators, has got to be one of the most likable main characters a book could create. She’s practical, God-fearing, driven, smart, and loyal. Meg, the second narrator, is witty and humorous to listen to, especially since you’re seeing things through the eyes of an eleven year old orphan. There are a few big reveals throughout the book, and around the midpoint there is a shift in storyline which will tell you how the book got its name. I saw some reviews say the book is a bit long, which doesn’t bother me. I see how the length may be necessary given the fact that the author had to bounce between two separate story lines and then merge them in the end. My only feedback about the length would be there is a lot of time and detail during the middle of the book (especially Meg’s time with her adoptive family) but less time spent on the ending, leaving things a bit rushed and many characters’ fate ambiguous. I found myself wanting more closure for characters Frances & Mrs. Tartt, as well as the boarders such as Flossy.
On a historical level, this book provides context for a dark time in America where society wanted to annex anyone deemed undesirable or peculiar, especially promiscuous women. Society was hyper focused on separating the pious from the “imbeciles” and punished anyone whose lives didn’t fit the perfect Christian mold. This caused characters like Frances and Mrs. Tartt to be obsessed with their reputation, and fear of tainted reputation is a huge factor in decision making amongst the main characters. Birdie, Meg, and Charlie seem to be the main characters willing to take huge risks and sacrifices for those that they love. This book inspired me to do some of my own research and I learned something new about American history.
