This Present Darkness by Frank Peretti (He also authored the sequel - Piercing the Darkness). The name I would use for my child would be TAL - Tal was the Commander of the Angelic Host in the Novel and his wisdom and commitment are attributes I desire in any offspring of mine not to talk of his strength.
I did this. One of my sons has the middle name Eden, the name of a ship in the Peter Matthiessen novel Far Tortuga. I was reading the book when he was born. It took a month to find a first name, and Eden had the right cadence for a middle name.
