Present Imperfect

Sequel to Past Imperfect. AU. Becky Snape and Gus Longbottom are thick as thieves and just as sneaky. What was supposed to be a lark – a trip to the past with Hermione's old Time Turner – turns ruinously wrong when they return to a dark, dystopian present where nothing is as it should be. (There IS a pairing but I hesitate to reveal it for reasons that will be clear at the end.)
