Allan Jenkins is the editor of the Observer Food Monthly. In his memoir, Plot 29, he recounts his life growing up in foster care with his brother Christopher. Their foster father introduced them to the joys of growing flowers which triggered Allan's lifelong love of gardening. As the boys grew up, their lives took different paths and Allan began to search for the answers to questions about his past. His book follows the course of a year in which he traces the story of his birth parents and finds solace tending his London allotment. Plot 29 - A Memoir is published by Fourth Estate.
