The first book is out and is called Ryann Watters and the King’s Sword. (Review coming soon!) The sequel, Ryann Watters and the Shield of Faith, is in the works.
His name ties in later when they are doing a search on a Bible software thing-a-ma-jig and by adding “double” to their search (because he has two Ns in his first name and two Ts in his last) they uncover a key clue to their quest for the King’s Sword. It’s kinda hard to explain, but there you have it.
“'Sire!' came a shrill voice from near the ground.
'Ah--Reepicheep!' said Peter after looking up and down and round as people usually did when addressed by the Mouse.” -- C. S. Lewis,
