Tough-O-Meter

We've got your back. With the Tough-O-Meter, you'll know whether to bring extra layers or Swiss army knives as you summit the literary mountain. (10 = Toughest)

The plot's a tiny bit tough to keep up with at times (probably because we're blinded by all that bright and shiny Crusader-garb), and the story also calls for a bit of background history.

Whether you're a history buff or you struggle to remember who the last president was, though, we've got your back and will cover much of the historical stuff throughout this learning guide.
