Glowing reviews greeted Anne Tyler's latest beautifully crafted novel exploring the frailties and foibles of humanity - what it means to belong to a family and to a country. Two Korean babies are adopted by Baltimore families; each year they celebrate 'Arrival Day' together, with a succession of ever-more elaborate parties. Competitiveness, misunderstanding and toe-curlingly funny moments unfurl in a novel with an apparently small domestic canvas and subtly large themes.
