What historical fiction doyou plan on using? FWIW - I have been reading the G.A. Henty books and find them to be a great source. There are some that have application in today's world as they are about Afghanistan.
We read Victor Hugo (with extensive study of cathedrals in conjunction with Hunchback), Alexandre Dumas (Three Musketeers and Count), The Song of Roland (with a study of the code of chivalry).
We scoured EBay for lots of classical books and Cliffs Notes. A lot of the classics are also online that you can download.
Here is one link: Bibliomania
For a good online literary analysis source, here is NovelGuide
For an online resource of early Christian text and Medieval Classics, here is a great site: Online Medieval and Classical Library
And if you want to start your day out right, try the online daily office (morning prayer, evening prayer, etc.): Oremus or The Daily Office. They will have the Psalm of the day, OT, NT, Gospel readings for the day, prayers, and hymns.
