A dizzying comedy about bad manners, Crazy Rich Asians offers refreshing new voyeurism for readers who are long tired of American and English aspiration fantasies. Mr. Kwan either knows, or at least pretends to know, how the very wealthy in Singapore, Hong Kong, and Shanghai flaunt their riches. This book amusingly mentions many different Asian cultures and mixes coarse slang from Malay as well as Cantonese and Hokkien dialects of Chinese. Mr. Kwan makes the most of them, providing a grand tour through a humorously exaggerated and ostentatious world. He knows how to deliver delightful pleasures, keeps the banter outrageously entertaining, the excesses absurd, and the details devilishly delicious.
