Which book to pick?

Right now I am trying to decide which book to pick for my book review. Do I pick a children's book that I like or do I pick a book I have been reading??? I am really thinking of picking a book from one of my favorite authors that I read for pleasure.   --Clive Cussler, Janet Evanovich, Douglas Preston and Lincoln Child, and others. I also like finding new authors like Spencer Quinn's Dog On It. Oh what is a girl to do with so many good books to choose from. You will have to wait for my next entry.
