Paperback, 205 pages Written in an upbeat and flowing mix of Spanish and English, Yo-Yo Boing is a symphony of dramatic, bilingual dialogue riding the current controversial wave of bilingualism. At a rapid tempo and with humorous gusto, Braschi’s poetic voice moves vigorously throughout the public and private spaces of the city-from the Upper West Side soiree to the Lower East Side tertulia, from the diner booth to the subway platform.
