Unlike the Moon, this volume only took a little more than 4 years in the making, but like the Moon, it has gone through numerous changes. However, through it all, the editors of this volume have expertly coordinated the numerous authors and extensive subject matter into a comprehensive review in which the reader is now easily re-introduced to a “forgotten friend,” the Moon. Their hard work and unwaivering dedication has made this volume a reality! My thanks goes out to them!
