I don't know if these quotes must be from novels or if they can be from anywhere except Kite Runner...
Martin Luther King, Jr. once said that "Darkness cannot drive out darkness, only light can do that. And hate cannot drive out hate, only love can do that."
Depending on how you read this, this quote could be applied to redemption and the nature of redemption.
“Love grows from the rich foam of forgiveness, mongrels make good dogs, and the evidence of God exists in the roundness of things.” - I Know This Much is True Wally Lamb “that's the funny thing about mazes: what's baffling on the ground begins to makes sense when you can begin to rise above it, the better to understand your history and fix yourself". - The Hour I First Believed Wally Lamb Arlen Bitterbuck: Do you believe that if a man repents enough for what he done wrong, than he'll get to go back to thetime that was happiest for him and live there forever? Could that be what heaven's like? Paul Edgecomb: I just about believe that very thing.
Arlen Bitterbuck: I had a young wife when I was eighteen. We spent the summer in the mountains, made love everynight. After we would talk sometimes till the sun came up, and she'd lay there, bare breasted in the fire light... that was my best time. »
-The Green Mile Stephen King
And just for fun :)He puzzled and puzzed till his puzzler was sore. Then the Grinch thought of something he hadn't before. Maybe Christmas, he thought... doesn't come from a store. Maybe Christmas, perhaps... means a little bit more! And what happened, then? Well, in Whoville they say - that the Grinch's small heart grew three sizes that day. And then - the true meaning of Christmas came through, and the Grinch found the strength of *ten* Grinches, plus two!

This isn't from a novel but it is one of the most powerful presentations of redemption that I know. It is a poem titled "Redemption" by George Herbert:
Having been tenant long to a rich Lord,
Not thriving, I resolved to be bold,
And make a suit unto him, to afford
A new small-rented lease, and cancell th’ old.
In heaven at his manour I him sought:
They told me there, that he was lately gone
About some land, which he had dearly bought
Long since on earth, to take possession.
I straight return’d, and knowing his great birth,
Sought him accordingly in great resorts;
In cities, theatres, gardens, parks, and courts:
At length I heard a ragged noise and mirth
Of theeves and murderers: there I him espied,
Who straight, Your suit is granted, said, and died.
I thought you might enjoy these, since some are from novels.
However, I will share my favorite quote on redemption, from A Tale of Two Cities.
It is a far, far better thing that I do, than I have ever done; it is a far, far better rest that I go to, than I have ever known.
This famous quote is from Sydney Carton, as he sacrifices himself to save the man married to the girl he loves, thereby redeeming himself.
