There are a lot of books suggested to go along with the current history cycle of Foundations.
Everywhere you look, there seems to be another list.
In the ten years we've been homeschooling with the help of CC, we've ever been able to read all the books that are suggested, so we settle for picking some of the titles each year, all of which are usually excellent.
We either read the books aloud together, or I will assign them for silent reading.
Right now, Adele is reading Arabian Nights an hour day during her silent reading time, one of the titles suggested on one of the reading lists for Foundations Cycle 2- The Middle Ages.
