The Kindle edition of What is the Gospel? by Greg Gilbert is currently free. I haven't read it yet, but it seems to have some good endorsements from people like Albert Mohler and Joshua Harris.
On Earth as It Is in Heaven: How the Lord's Prayer Teaches Us to Pray More Effectively by Warren Wiersbe is also free at the moment, though I know little about the book or the author.
Just in case anyone's interested.
