Nuna gets a Chance by RM

I read a story called Nuna gets a Chance.
Nuna said I am the fastest in the world.
Her new shoes were dirty.
Nuna's brother was a messenger.
Her brother Inti had to deliver a message.
Nuna had to deliver the code because her brother got hurt.
She saw a footbridge.
She was far away from the town.
Nuna fell to her knees when she fell in front of the king.
She was happy she was a messenger.
