Twelve-year-old Maisie is an artist.When she's in front of her sketchbook or apprenticing at Glenna's Portraits, the family-run art shop her grandmother started, the world makes sense. She doesn't think about Calum, her brother who mysteriously left home and cut ties with her family six years ago, or her parents' insistence that she "broaden her horizons" and try something new--something that isn't art.

But when Glenna's Portraits falls on hard times, Maisie's plan to take over the shop when she's older and become a lifelong artist starts to crumble. In desperation to make things right, Maisie runs away to London to reconnect with her adult brother, hoping he might be the key to saving the shop. But as Maisie learns about her family's past from Calum, she starts to rethink everything she's ever known. Maisie must decide not only if saving her family's art shop is worth it, but if she can forgive her parents for the mistakes they've made.
