Dragon Wing is book 1 in the completed Death Gate Cycle of 7 books. The first book contains a complete story but there is quite obviously something more complex going on. The best part of this book is the world building - it is original, even after all these years. The characters are also fairly well written and complex. Even the dog has his own personality. The book starts off with an assassin in what is superficially a medieval world and ends up with a variety of elves, dwarves, humans, an "adorable" manipulative little child, wizards of various kinds, a man with bandaged hands (and his dog) in a world that isn't all that medieval anymore and on the cusp of change. Book 1 takes place in the World of Air, which is a world of floating continents with a contraption (of unknown purpose) called the Kicksey-winsey worshiped and maintained by the locals. Travel between these floating islands is via dragon back or airship, and the local currency is barrels of water or their equivalent in coin. This adventure is a fun, action packed romp through an interesting realm. If you want to know what happens in such a fascinating world, you are just going to have to read the book (and the rest of the Death Gate Cycle).
