I'll have to wait and see what this book would be about. If it's inspirational and done in good taste, then maybe it's a good thing for all of them. If it's a tell all type of book, not so much

.
I had written to the publisher and asked about her cook book, and all they told me (although someone else indicated they got a much more personal note back from them and no way were they going to be publishing for her) in a form letter was there was a book in the wings in the future..but I thought they meant the cookbook.
Edit to add I found the write up on their site:

Description:
The 9.8 million viewers of TLCs Jon and Kate Plus Eight recognize Kate as the perky and practical mom of eight who has come into their homes for over 100 episodes of her familys hit reality show. Although the show has made her face recognizable, theres another part of Kate the viewers havent seenher heart. In I Just Want You to Know, Kate reveals a less familiar spiritual side. . The book covers the three years her family lived in their Elizabethtown home, a period Kate considers one of the happiest of her life. It shows the parents of eight kids (all under the age of six) transitioning from the chaos of caring for infants to the structured days of a home filled with budding preschoolers. During that time, the family underwent major changes: From diaper changing to potty-training the sextuplets From only traveling a few miles for a rare meal out to flying to Hawaii to renew their wedding vows From Kates need for control, to learning how to be flexible From watching a child who couldnt spell, singing B-I-B-I-B (the Bible song), to their first child growing in her faith and praying to ask Jesus into her heart From Kates first speaking engagement (she was afraid to fly) to her book tour From a desire for a normal family life that didnt include outside help, to a desire for a normal day without public attention.
