Is there going to be another silverwing book?

Answer 1

By Kenneth Oppel. There are three in the series and one standalone so far: Silverwing, Sunwing, and Firewing are all about Shade and his various friends/relatives. The fourth, Darkwing, is set in prehistoric times and features gliding bat ancestors known as "chiropters," one of whom, Dusk, learns how to fly. There will probably not be another book about Shade, due to the ending of Firewing. It is possible but unlikely that the author might write another standalone like Darkwing. If you liked this author's writing, he has also written Airborn, Skybreaker, and Starclimber, which feature human characters and are for a teenaged audience rather than children.
