"Cabbagehead" is the story of a friendship between an inhibited human and an enlightened plant. It tells of Bradley Peterson, who has avoided being known or engaged in life through his fifty years of existence. Mistreated by his parents, bullied by his duplicitous wife, and long overwhelmed even by mundane events, Bradley has retreated to an uninspiring interior life. His only contentment is in gardening--until the day a plant, looking like a large and unlovely cabbage, speaks to him. Encouraged by the wise and persuasive Cabbagehead, Bradley becomes more assertive at work; reconnects with his children and father; stands up to the machinations of his scheming wife; and embraces a new, fulfilling life. But Bradley is alarmed when he learns of Cabbagehead's plan for him--saving the planet from ecological disaster.
