The chronicles of Narnia, to be read in whatever order you feel is correct (but there is really only One True Order), are now for a short time available for $1.99 each in Kindle form. This probably only applies to US buyers, but I don’t know that for a fact.
The Lion, the Witch and the Wardrobe (Chronicles of Narnia Book 2 BUT REALLY BOOK 1)
