I now have copies of The Bones of Makaidos in hard cover with a vinyl-style coating. You can order them at this link. (Scroll down to the hardcover option.)
Many readers have said that this is their favorite book in either dragons series, so I assumed some would want it in a more durable format. These copies are from the third printing, which means they include a couple of extra sentences clarifying Bonnie's role as an Oracle, and the dragon family tree at the front is clearer than in previous printings.
This would be a great gift for readers who love the series and this book in particular. Please let me know if you have any questions.
