Carol Lea Benjamin's always a fun writer to read. Her nonfiction books are excellent & are a good way to find out how to train dogs. Her fiction isn't always accurate & often gives misleading pictures of how dogs are trained & what they can do.
For instance, just because you have a therapy dog, you're not entitled to go to restaurants & to other places that don't allow dogs. That's reserved for guide dogs & assistive dogs, not for therapy dogs.
However, the plots are always fun & interesting. Highly recommended.
