Sixteen Slytherins. One ancient grimoire. One ritual they absolutely should not have performed. You and your fifteen closest friends go to sleep expecting sixth year and wake up in 1970—with new surnames, teenage versions of your parents walking Hogwarts, and absolutely no idea how to get home. Now the sixteen have three rules: find a way back, don’t expose who you really are, and do not change the future. Simple. Except the raw dark magic you buried years ago is waking up again, your parents are getting suspicious, the Marauders are everywhere, and apparently sixteen teenagers are remarkably bad at leaving history alone. (Messed up the first one.)
