I've found the devotional Seeking the Face of God: Praying with the Bible Through the Year (ISBN 978-1592557684) a great devotional. The book includes a short, personal devotional service including Invitation, Bible Song/Psalm, Bible Reading, lectio divina, free prayer subjects, closing to prayer, and a blessing. It takes a bit of a reformed perspective but would work well for many even outside the reformed tradition. It's published by Faith Alive Christian Resources/Calvin Institute of Christian Worship. Written and compiled by Philip F. Reinders with foreward by Eugene Peterson. It would be great to have this as a devotional in Logos, and I did notice the Kindle version (and other ebook formats) became available in the last several months.
