Mission to America Book

Well, it was a mixed bag.
I'd give five stars just for the first section of the book which explains the Apostles lifestyle and religious beliefs. What a wonderful, novel religion. Had me laughing--I thought I'd never see Candida (yeast overgrowth) in fiction, let a lone a religious setting! So much of the matriarchal apostles was familiar...I mean I think he concocted a believable amalgam of feminist, health-nut spiritual beliefs; and he did so tenderly (kudos for that).
Once the Apostles hit Show Shoe, Colorado, on a quest to find converts to bring new stock into their dying flock, the story looses it's appeal. Part of me had no interest in the lifestyles of the rich and famous, which made it hard to "immerse" myself into the story. I also found myself lost a lot, having trouble following how a character moved into a new conversation or situation. This really troubled me, and I am at a total loss at how to describe it well. Maybe a lack of description and setting, or poor segues?
They story redeemed itself by wrapping itself up well.
