Bøker i Grampa Was an Alien-serien

The final chapter in Grampa's story; did he imagine it all? Was it all real, or did he dream it? Daughter, Janet still doesn't believe it. Yet another story, about to be told on the occasion of Milly's 12th birthday, compels Janet to tell her father to "stop pretending the aliens were real", otherwise she might be forced to "talk to someone about it". Grampa Ethan needs to put up or shut up. Can he confirm that it was all real? Or is he just a crazy old man. He resorts to the one final thing that will prove it, if it works. Maybe. No one is prepared for what happens next.
