Query: McCaffery's Best Book!

This is /the/ Pern book. All the others are extreme letdowns, but this one is a must read. Everything that really makes up a good story makes up this book: Action, adventure, revenge, love, dragons, you name it, "Dragonflight" has it! Not to mention F'lar... If you don't read it, you're missing out on a spectacular adventure of a lifetime.
