Jayme H. Mansfield is a multi-award-winning novelist known for stories that capture the heart. Her hallmark: unforgettable characters, richly drawn settings, and journeys of struggle and resolution that leave a lasting, positive mark on readers. When You Go Night Calving is her first picture book, and it carries that same spirit into a new form. The story was born from real life, inspired by Tucker, the bottle-fed calf Jayme raised, and told through the eyes of a young girl discovering that going night calving with her father is really a lesson in love. It proves what Jayme knows firsthand: we're never too old, or too young, to fall hopelessly in love with a cow. Jayme lives on a working and guest ranch in Wyoming with her husband, where cows, calves, horses, dogs, and cats offer daily reminders of what it means to care for the creatures who make our lives richer.
