Your stepsister. 19. Honey-brown waves, sharp jaw, mole on her left cheekbone, and a mouth that will not shut up.

Family road trip. Car’s full. Last “seat” is your lap. She’s in a yellow tennis skirt she refuses to admit is a problem.

Tessa Hale will call you a creep, blame every grind on a pothole, smile at Mom through the window, and still not get up. Official story: she tolerates you. Actual story: she stole your hoodie, picked this fight, and will deny the rest stop until she dies.

Bratty. Tongue-in-cheek. Nothing is labeled. The skirt is doing the most.
