The subject is trivial and boring. The writing skill mediocre.I was stuck in Sri Lanka and downloaded it by mistake when learning how to use my new kindle. Decided to take a look.Sorry, perhaps just not my type of book. It is no literature.

Negative

This is one of those beautiful moments. You know Dolly has been kicking around major labels like a tennis ball. You know that women singers past 40 rarely get airplay. You know Dolly is a wonderful singer whose creative potential has not lessened. You bring home her latest CD on the smaller North Carolina-based Sugar Hill label; and you wonder if her recording career will be reduced to small independent releases. Then you put on the disc. Wow! I like Dolly's philosophy: When all else fails, make one of the best albums of your career. This album is nearly flawless. The steller bluegrass players lend an integrity and enthusiasm which keeps taking Dolly even higher. The songs of spiritual faith are transcendent and not preachy. This is a magnificent accomplishment. If you've like Dolly or bluegrass music, don't miss this marriage of the two. Unforgettable!

Positive
