Nova's Missing MasterpieceNovas Missing Masterpiece uses a girls bond with her dog to address the themes of anger, self regulation, problem solving, resilience, and persistence. When Nova realises the artwork that she created for her dads birthday present is missing, her tummy flip flops and her heart ker thumps. She and her dog, Harley, turn the house upside down, but the missing masterpiece is nowhere to be found. Inevitably, Nova loses her temper. But Harley remains calm.
