Bel Canto, by Ann PatchettRead about another entry on the list.
In an unnamed Latin American country, diva Roxanne Coss has been hired to sing at the birthday party of Katsumi Hosokawa, the opera-loving head of a Japanese electronics company. The party takes place at the villa of the country's vice-president, but is interrupted by guerillas, who hold the guests to ransom. It cannot end well.
Bel Canto is one of Joyce Hackett's top 10 musical novels.
