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)

Although the narrative jumps around in time quite a lot—and moves in and out of a lot of different people's minds—Erdrich makes the temporal and character shifts really easy to follow by putting the year in question (and, if relevant, the character "speaking") at the top of sections and chapters. So, it's not totally smooth sailing, but really, it's not that hard to follow what's going on in terms of the narrative's twists and turns.
Beyond that, since a healthy portion of the narrative is written in the first-person, the language is pretty straightforward and straight talk-y. So, we're going to say this one doesn't involve going too far up the mountain—and, bonus, you still get a great view.
