The book page doesn't have the authors, nor the number of pages, likely because it was imported from Amazon US https://www.amazon.com/Saudade-Jambo/...

The Amazon BR page contains a lot more info, but some are still wrong https://www.amazon.com.br/Saudade-Jam...

Pages: 128
Authors: Melissa Garabeli & Phellip Willian
