Beckeye asked and I answered, but after thinking about it, I realized how inadequate my answer was. Here is the synopsis of Bel Canto:
Somewhere in South America, at the home of the country's vice president, a lavish birthday party is being held in honor of the powerful business man Mr. Hosokawa. Roxane Coss, opera's most revered soprano, has mesmerized the international guests with her singing. It is a perfect evening - until a band of gun-wielding terrorists takes the entire party hostage. But what begins as a panicked, life-threatening scenario slowly evolves into something quite different, a moment of great beauty, as terrorists and hostages forge unexpected bonds and people from different continents become compatriots. Friendship, compassion, and the chance for great love lead the characters to forget the real danger that has been set in motion...and cannot be stopped.
It is a gorgeous book, and it ends the way it must. I cannot recommend it highly enough.
