Get a semi-free copy of Scott Klusendorf's _The Case for Life_ from the publisher, Crossway.
I say "semi-free," because you must fiill out a survey and agree to get weekly emails from Crossway (but that's not necessarily bad--I received this offer in an email from them) in order to receive it. However, the book is the full, unabridged, 256-ish page edition whose Kindle mobi version is $9.99. And with this freebie you get your choice of mobi, and/or ePub, and/or PDF versions.
My only beef with the offer is that the survey will take probably 15 minutes or more if you give truthful, thoughtful answers. But remember that this book would cost (what I would consider) quite a bit of money to buy it. Oh, and this book is highly rated, at Amazon at least.
