Query: Bitter disappointment

I love books and am guilty of reading many of them because they were recommended by friends or by book reviewers. This one was recommended in a book review, and I wish I'd skipped both. The stories of the individuals with whom Timoleon, the titular subject, crosses paths, are sympathetically described, but there is not enough about them or their futures to be satisfying. And Timoleon's fate is just too heartbreaking for an animal lover. Skip this book if you are at all tender-hearted.
