These two vintage novels are great for reading and adding to your book collection. When reading, handle them gently due to their age and the wear they've experienced. To maintain them, store them in a dry and cool place away from direct sunlight. Avoid getting the pages wet as the staining and soiling could spread. If you notice any loose parts, it's best to consult a professional book restorer. Since 'Stairway to a Secret' is an ex - library copy, it might have some library - specific markings, but that doesn't affect the story inside. Enjoy exploring the worlds these books have to offer!
