The chalk artist - Allegra Goodman

Collin is young, creative, and unhappy. A college dropout, he waits tables and spends his free time beautifying the streets of his hometown, with a box of chalk. Collin's art captivates passers-by with its vibrant colours and intricate lines - until the moment he wipes it all away. Nothing in Collin's life is meant to last. That is, until he meets Nina.
The daughter of a mega-rich virtual-reality mogul, Nina is trying to give back as a high school teacher - but her students won't listen to her. When Collin enters her world, he inspires her to be a better version of herself. Nina wants to return the favour.
