I have the following Highlights Top Secret Adventures Guides.  Each book is a 32 page paperback.  They are packed with colorful photos and factual information on each country.  They all carry isbn's that match the system here, thereby being worth 1 credit each.  I have 13 of them and you can have them all for 4 credits.  That's 3 for 1 with a bonus extra book.  They are all in postable condition.  They all look new actually.  They are geared toward elementary age and would be fantastic for homeschool lessons.  These would also be great books for grandparents to keep at home to have something fun and educational to read with the grandkids when they come over.

Some of these don't have cover images, but they all look nearly identical.  So for the covers you can see, the rest will be very very similar.  I also have a 14th book that is pending on someone's WL right now.  It is Guide to Brazil (Highlights Top Secret Adventures) :: Marion Morrison.  If the person doesn't want it, I'll throw it in as a freebee.  There's only one person wishing for it, so I'll know one way or the other in 48 hours or less.  Please PM me and post here as well.  Thanks.  I'm headed out the door, so if I don't answer right away, don't worry, I'll be back soon.
