There is no Ad Stellae Books edition of Sylvia Engdahl's best-known novel, the Newbery Honor book Enchantress from the Stars, because the rights to it are held by Bloomsbury (which bought Walker, the publisher of the 2001 hardcover edtion). A new large-size paperback, along with Kindle and epub editions, was issued by Bloomsbury in April, 2018. Though often given to younger readers this book is best liked by those in the 8th grade or older.
