The Great Wall of Lucy Wu by Wendy Wan-Long Shang

Lucy Wu, aspiring basketball star and interior designer, is on the verge of having the best year of her life. She's ready to rule the school as a sixth grader and take over the bedroom she has always shared with her sister. In an instant, though, her plans are shattered when she finds out that Yi Po, her beloved grandmother's sister, is coming to visit for several months -- and is staying in Lucy's room. Lucy's vision of a perfect year begins to crumble, and in its place come an unwelcome roommate, foiled birthday plans, and Chinese school with the awful Talent Chang.
