Our Crumbling Ivory — Rick Cook

It's Chester Lansing's final year as an undergrad, and he's more than anything ready to put the rote classwork behind him, to begin his Graduate program and become a teacher. But something odd is happening on campus this semester, and Chester is the only one who seems to notice it. As the year wears on events continue to change around him, personal memories become indistinct or vary greatly from others' memories. Has Lansing simply lost his mind or is something really going wrong?
