I read this book as a kid in the 1970s. I don’t remember much, except that a teen boy wakes up in the morning and soon realizes that nobody can see him. He thinks he’s dead. He can’t really interact with the world, but he does manage to ride a bus without falling through the floorboards. It might be that he never existed–I seem to remember that people weren’t wondering where he was. It might have the word “disappear” in it.
Stump the Bookseller
New format, same book stumper solving.
Is it The Dog Days of Arthur Cane by T. Ernesto Betancourt? I know he ends up a dog, but doesn’t it start with him being invisible? (If it’s not that, maybe it’s another by that author.)
Lee Harding’s Displaced Person?
OMG YES!!!! This is the book. I’ve been trying to identify it for decades. Thank you so much!
