A copy of Allies, by Alan Gratz. Hard copy preferred, but E-reader ok as well.

I would just say to please be aware that these classes are about warfare and a major military history event. One aspect of this is to talk about weapons from the corresponding era, and to discuss advancements in military technology. I don't handle any firearms personally, but we do discuss weapons and technology and I show pictures and videos when appropriate.

If your learner is sensitive to this kind of subject, and may get frightened or upset upon seeing a picture of a rifle, cannon, tank or bullet, then this may not be the class for them. This is a class about military history, and there is no way to avoid this, so please take this into account before signing up.
