You don't even need a kindle, you can just download an e-reader to your computer and you're good to go.
Here's one I just downloaded for some light reading (is that bad? Doesn't everyone need some light reading from time to time?) (Disclaimer: I have not yet read it, so I cannot vouch for the language or themes in it)
And of course, I got a free cookbook too! Time for some salad experimentation here - since it's too hot to cook anyhow. And somehow, I always end up perusing cookbooks on fast days. Perhaps silly of me, but that's what I do! The question is, can I get my kids to eat these salads, as they are "mixed foods"?
Enjoy your freebies!
