Rich people problems : a novel / Kevin Kwan.

Enhanced descriptions from Syndetics:

Kevin Kwan, bestselling author of Crazy Rich Asians and China Rich Girlfriend , is back with an uproarious new novel of a family riven by fortune, an ex-wife driven psychotic with jealousy, a battle royal fought through couture gown sabotage, and the heir to one of Asia's greatest fortunes locked out of his inheritance

When Nicholas Young hears that his grandmother, Su Yi, is on her deathbed, he rushes to be by her bedside-but he's not alone. It seems the entire Shang-Young clan has convened from all corners of the globe, ostensibly to care for their matriarch but truly to stake claim on the massive fortune that Su Yi controls. With each family member secretly fantasizing about getting the keys to Tyersall Park-a trophy estate on 64 prime acres in the heart of Singapore-the place becomes a hotbed of intrigue and Nicholas finds himself blocked from entering the premises. As relatives claw over heirlooms, Astrid Leong is at the center of her own storm, desperately in love with her old sweetheart Charlie Wu, but tormented by his ex-wife-a woman hell bent on destroying Astrid's reputation and relationship. Meanwhile Kitty Pong, married to billionaire Jack Bing, finds a formidable opponent in his fashionista daughter, Colette. A sweeping novel that takes us from the elegantly appointed mansions of Manila to the secluded private islands in the Sulu Sea, from a schoolyard kidnapping to a gold-leaf dancefloor spattered with blood, Kevin Kwan's gloriously wicked new novel reveals the long-buried secrets and rich people problems of Asia's most privileged families.
