Book 4 in Around the World in 80 Mysteries & Book 10 in the popular Carole Marsh Mysteries - Real Kids Real Places. Fictional kids discovering real life places in the form of a mystery/scavenger hunt. Such fun books! See photos for a few issues with book 10: the first couple of pages have some spots and there is discoloration specs throughout the book that does not affect it's readability. No writing or markings. Book 4 is in good used condition. A bit of lift to the cover, no markings. See my other childrens, juvenile, vintage and homeschooling books!
