At twenty-one, Justin Kloster has it made: one more year of college and then happily ever
after with his sweetheart Megan. Then his forty-year-old self shows up to prevent Justin from
making terrible mistakes that will lead to an eventual nasty divorce with Megan.
Turtledove
tells the story twice: once from the Justin-21’s point-of-view and once from that of
Justin-40. Together, the stories form a short novel-length work that can be read in either
order.
