The gritty, compelling New York Times bestselling novel of star-crossed lovers and circus life, set in Depression-era USA.

Sam, Bonzi, Lola, Mbongo, Jelani and Makena are no ordinary apes. These bonobos, like others of their species, are capable of reason and carrying on deep relationships - but unlike most bonobos, they also know American sign language.

THE NEW YORK TIMES BESTSELLER FROM THE AUTHOR OF WATER FOR ELEPHANTS.
