Spring has arrived in Brooklyn, New York, but winter refuses to let go. Sleet, snow, and even a tornado batter the city. Mr. Ross, the science teacher, believes climate change is the cause, but classmates Edward, Feenix, Danton, and Brigit suspect older, magical forces are at work. When a peculiar character calling himself Superintendent Tiltersmith appears with a keen interest in the foursome, their suspicions are confirmed, and they're swept up in a battle of wits and courage.

The friends must protect a set of mysterious tools belonging to the Lady of Spring. If they can free her from her underground prison, winter will end. But if the Tiltersmith steals the tools, he will keep the Lady in his power and upset the balance of nature forever.

Perfect for readers of Madeleine L'Engle and Susan Cooper, The Tiltersmith returns to the world of Amy Herrick's acclaimed Time Fetch in a timely, exciting stand-alone adventure.
