Ex Input:
This book was OK although the title kind of leads one to think it's a true story. There are many grammatical errors and missing words (plurals). For example, the term "kitten" should have been "kitt" in paragraph 3 (p. 217). The author does describe his feelings about being able to travel with dogs while he can no longer walk. He explains how he's going to use this experience for others too. At times, it seems as though some phrases or sentences were thrown together hastily.

Ex Output:
Good Review


Ex Input:
This book did not have much helpful info. It was basically about getting a horse to do anything. She had way too many tips on how to train your horse. There are ways in which all three children can learn. I found myself skipping over those parts because the information was nothing new. Not worth buying.
