Just lovely. Hanff is charming, witty, touchingly generous, and enthusiastic about books, her correspondents are grateful, skillful at their trade, friendly and welcoming, and offer tiny windows into 20th century British history (i.e. post-WW 2 rationing, screaming Beatles fans).
How can an ending so sad, seem so perfectly ordained as the bittersweet stuff of literary fiction, somehow manifest in the non-fiction sphere of real life epistolary?!
