My favorite part of “The Chronicles of Narnia” series is the love between Lucy and Aslan.
He is the depiction of Jesus. And of God. He is massive. Powerful. Immutable. His ferocity is frightening to others.
But not to Lucy. She loves him. She buries her face in the beautiful silkiness of his mane, riding high over the mountains of Narnia. Death is certain should she fall, but she is undaunted. Settled on his broad shoulders, her fists clutch that golden mane. Because it is Aslan that carries her, Lucy is carefree.

His frame is strong. Unwavering. Secure. Unassailable. He never falters. Never misleads her. Never abandons her. He never lowers her to earth anywhere short of stable, sheltered ground.

He is insulating. He speaks to her softly, words rich in wisdom. All at once, his heart a blend of tenderness, intensity, and protectiveness. In there also, his own pain.
And so she loves him.
An excerpt of their reunion, from “Prince Caspian”: The Return to Narnia …
And then—oh joy! For he was there: the huge Lion, shining white in the moonlight, with his huge black shadow underneath him.
But for the movement of his tail he might have been a stone lion, but Lucy never thought of that. She never stopped to think whether he was a friendly lion or not. She rushed to him. She felt her heart would burst if she lost a moment. And the next thing she knew was that she was kissing him and putting her arms as far round his neck as she could and burying her face in the beautiful rich silkiness of his mane.

“Aslan, Aslan. Dear Aslan,” sobbed Lucy. “At last.”
The great beast rolled over on his side so that Lucy fell, half sitting and half lying between his front paws. He bent forward and just touched her nose with his tongue. His warm breath came all round her. She gazed up into the large wise face.
“Welcome, child,” he said.
“Aslan,” said Lucy, “you’re bigger.”
“That is because you are older, little one,” answered he.
“Not because you are?”
“I am not. But every year you grow, you will find me bigger.”
