Educational & Interesting Bathroom Reader
Format: Paperback
I bought this for my husband for Christmas given that he loves history. I figured it’d be a hit as a bathroom reader… I was right and it’s become a fixture right next to the toilet paper! He likes that it challenges him to think. Now there’s no need to take his phone into the bathroom!

BCE? No, it is BC!
Format: Paperback
I love history; there is a lot in this book I did not know. It is definitely a challenge and a great way to learn. I took off one star (considered taking off two) because the author uses the non-Christian term of BCE. I HATE seeing that instead of what it really is BC - before Christ! I wonder if he is an atheist.

Very informative
Format: Paperback
Bought this for my son, and he really loves this book. He reads it over frequently. I recommend it if you have a reader that also wants to learn facts about history.
