[EX A]: Bad review

[EX Q]: If you like reading about self absorbed characters this isn't the book for you. I will not be recommending it. The writer is one to watch and if there are other books of his worth reading give it a shot but check out what you're buying. Not some &#34;greatest hits&#34; crap. I'm sure he has some redeeming qualities however it's hard to root for. Sorry author. It's been an agonizing 2 months having waited till now only to want my 2.99 back.
[EX A]: Bad review

[EX Q]: I bought this for my granddaughter to help her understand how the world works. It really opened up a lot of questions she had about history from a very young age. You can't beat &#34;History&#34; in your home. Especially an English teacher. Highly recommend both. I would probably buy it as a gift too! A great educational tool.
[EX A]:
Good Review
