Seeker at Cassandra Marsh- Olive M. Anderson

[Monica]

Hello! I would like to request that a cover be added to Seeker at Cassandra Marsh by Olive M. Anderson. I recently picked up a copy, and it's an old book published in the 70s without much info online. Any info added would be appreciated! Thanks!
