Mia loved her big, bright room until she had to share it with her new brother. With Brandon's toys, books, and even underwear taking up space, Mia has finally had it. "I'm moving out!"

Tackling the oh-so-relatable topic of finding a space of one's own, Mia will inspire siblings everywhere to work together as a team. Because sometimes the best place of all is a shared one.
