Space Mouse [EPUB ebook] 

BMW is an unusual mouse having remarkably keen hearing and enormous ears that he has been part of our space agencys search for messages from outer space.
Logically, with the billions of galaxies out there, it would be peculiar if our earth was the only one with people. Actually, BMW failed to hear any messages from space while orbiting in his space capsule, but what he did hear lead to his being honored by our president. His story is told by a professor he befriended by chance after making a nest in the professors old car called a BMW.
