Prologue

After escaping the Speed Force, Barry and Iris are unable to rekindle their relationship. Deciding it's best to give each other some space, Iris leaves Central City to spend time with Wally in Blue Valley and Barry travels to Earth-38 to spend time with Kara. National City welcomes the Blur back with open arms but Cadmus fears the Scarlet Speedster. After realising she's in love with Barry Allen, Kara Danvers must learn to open her heart again. Meanwhile, Lillian Luthor plots to destroy the Girl of Steel and Scarlet Speedster once and for all.
