I too am a huge fan of the Amber series. I don't think Zelazny's estate has managed that asset very well though. See the Bettencourt novels and the controversy relating to their publication as an example. Or how rarely one will find Zelazny's works on the shelf at most brick and mortar bookstores compared to his contemporaries. I wish you well in your quest! I'd love to see this series get a second life.
