AU: Blair is devastated. Her most beloved brother, Dan, is going to war and she is left behind by herself. Or, she has Serena, but then Blair does the unthinkable: She cuts off her hair and joins the army as well, disguised as a man. Who is the mystery man on the train? How does she handle to fall in love with a man who thinks she's a man, too? Chair. Begind in 1914, The Great War

Blair is sent to spend her whole summer with Bass Family. She's not very excited about this because she's been crushing on chuck for awhile and well they hadn't seen each other for almost a year. A lot changes in a year, but Blair's feelings never changed. Will her and Chuck handle living under the same roof? Will fireworks fly or will butterflies die?
