The Walls of Air by Barbara Hambly

4.0

Rudy and Ingold set off for the Hidden City of Quo, both of them will be sorely tested during this Journey. Meanwhile, back at the keep, Gil uses her scholar's training finding out more about the Keeps secret operations. See also stops the doors from being thrown open to the Dark. A good adventure, it's above average when compared to second volumes in other series. I'd forgotten about this book, so it was like reading a new book.
