The Power of a Whisper: Hearing God, Having the Guts to Respond is now
free at Kobo for Canadians, at least, and since it's a Zondervan book, will probably also be showing up at Sony and perhaps B&N later.
I have to say that whatever the actual content may be, I quite like the title of "Beer is Proof God Loves Us" above.
ETA: Now
free @ Sony. US-only.
