潔魯夏‧阿波特(Jerusha Abbot)是名十八歲的孤兒，大家都叫她茱蒂，就在她準備離開孤兒院獨自生活之際，意外出現一位善心的神秘贊助人，願意資助她上大學，唯一的條件是她每個月要寫一封信，報告她的生活。不料她充滿坦率、幽默與想像力的信，深深吸引了這位神秘的仰慕者。他到底是誰？從寫給長腿叔叔的76封信，告訴我們這個有趣故事。 Jerusha Abbot has spent all her 18 years in an orphanage. Just when they were about to send her out into the world on her own, a benevolent Trustee offered to pay her way through college. The only condition was that she had to write regularly and report on her progress. Little did she know that her humor, honesty and wit have captivated a secret admirer. Who is he and who is the trustee whose name she doesn’t know? Her letters addressed to Daddy-Long-Legs tell the story.
