Tras La Pista del Ruiseñor

"Jasper has been waiting all spring for his beloved nightingale to return to his garden to sing. But the bird does not arrive, nor does his sister Rosie. His parents seem sad and worried, so without hesitation, he grabs his backpack and his beloved Book of Birds and sets out on a journey to find them both. The expedition will take Jasper through the countryside and the city, and he will meet a lot of people who, like him, are also looking for lost things. It's by helping his new friends that Jasper will begin to realize that he may not find what he's looking for--but he'll realize that even in the darkest of moments, you can hear the song of the nightingale."--Provided by publisher.
