Bat and his best friend, Israel, know they need to convince Mr. Peña to change his mind about class pets--and when a business of friendly ferrets arrives at Bat´s mom´s veterinary clinic, they think they´ve found the perfect pet to do so. But when they discover that their classmate Lucca also doesn´t like the idea of an animal in the classroom, Bat starts to worry that things will never be the way they were again. The beloved series that began with A Boy Called Bat continues with this fourth book featuring an unforgettable young boy on the autism spectrum.
