Ace Double Books

by Andre Norton

There are 12 Ace Double Books (containing 15 titles) written by Andre Norton.

ACE then released another pair of titles "Star Hunter" & "Voodoo Planet" combined together but not considered an ACE Double book: although some sites have listed them as such (ACE released two prints).

If like me you have an interest in ACE Double books check out
