I didn’t even know this book existed until I was doing research for my review of Tear of the Gods. When I was working on that, I discovered that there were originally plans for one or two more games after Return to Krondor, which was extended and novelized by Feist after the game came out.
This book, Jimmy and the Crawler, takes place almost immediately after the end of Tear of the Gods, and after the games were cancelled, there was not enough interest or money. Feist had originally planned to write two novels to round out the Riftwar Legacy Saga, but in the end all we got was one novella.
