I read Charlotte's Web and Secret Identity (Shredderman #1) with my son. The 5th Wave 5* I've been really into post-apocalyptic/dystopian and I loved this book. I've heard not so great reviews about the next two books in this series though.
The Girl With All The Gifts 4* Very interesting ending which made me bump it up from 3* yo 4*.
The Scorpio Races 4* I loved the writing. The story was weird but I have a huge crush on Sean Kendrick.
I cried myself to sleep for days after reading Charlotte's Web. I haven't been able to re-read it, or see the (1973 animated) movie since.
I was a little concerned but I think he didn't quite understand what happened exactly. He's only 6. We will definitely do a reread when he (and his sister) are older.
