There is no shortage of summer reading programs. You don't have to venture any further than your own local library to find something cheap and fun to do. But if you are interested in an Around the World kind of theme with fun printables, maps and guides, you may want to check out the Read the World Summer Book Club.
Obviously you're not about to use them as source material for a research paper, but how well do you trust unofficial books? Many of these books exist as biographies or guides to media like movies or TV shows and are simply without permission from the original source. Most digital media already exists in this format, so what's the big deal?
Fans of A Song of Ice and Fire, take a deep breath: the spinoffs that we've all been hearing rumors about are indeed in discussion. George R.R. Martin says that he is in talks with HBO writers about a FEW spinoff ideas.

Jessica Seinfeld's cookbook, Deceptively Delicious, has been on my to-read list for a long time. When I finally checked it out from the library, I skimmed through the book and realized that the recipes were pretty much the same ones you will find anywhere. The only twist is that they incorporate vegetable purees in them to get kids to eat their vegetables. This is fine; I'm happy to pack extra nutrition in muffins or macaroni.
