I don't think I'll be able to give this book a decisive rating until I'm able to read the second half of the series. McKinley does a spectacular job developing the opening premise of misunderstandings between humans and pegasi. The realistic details with regards to body language, accent, and cultural values are superb. I couldn't help but feel that the ending was rushed, however, Pegasus feels more like an installment than a complete object in an off itself. Even with this criticism, half of a Robin McKinley book is head and shoulders above most of the whole books I've read lately.
