Query: Second Wind

Did Mr. Francis get a new editor? Did Mr. Francis really write this book? Usually the author writes with an ease of dialogue, illustrating his characters for the reader and delivering perfect timing. The relationship with Jett was clumsy and a bit of a surprise. I'm sure the weather information was accurate because Francis ususally does good research, but he's better at writing mysteries and adventure with real horse plots, not just throw in a horse because his name is associated with that style. Very disappointing. Did he really write this one?
