Be sure to get lined up to be able to offer Leland Ryken’s forthcoming biography, J. I. Packer: An Evangelical Life (Crossway, 2015), as a pre-pub as soon as you can. It is, according to Mike Reeves (Theological Advisor for UCCF), “now the definitive, most up-to-date biography of J. I. Packer.” Don't let Amazon beat you to it with a Kindle edition!
