Twilight scurried through the store, her eyes twinkling between each cover which captured her hungry eyes. Filly philosophies in a post-unification dichotomy? Biomedical analysis of the unicorn horn? Chromosomes and you: What makes a pony a pony? She scurried straight past "Heart of Friendship". She didn't need to read children's stories - they were about as high a prioritisation as colouring books and cooking guides.
Something glimmered in her eyes and she spun around on all fours. Eyes wide, mouth open, she pottered towards her destination. Sitting on deftly on her flank and looking to her parents, she pointed and proclaimed "That one!"
Thus the magical book horse was born.
Adorable.
