The Dream War — Jaime D. Buckley

When Maisie is awakened by a nightmare, her loving parents rush to her side to soothe her. Her mommy encourages her to think happy thoughts before going to sleep, hoping that would bring her more pleasant dreams. Big sister Annabelle observes the attention Maisie gets, and she gets more frustrated the next day when Mommy and Daddy are SO interested in every detail of Maisie's dream. Annabelle decides to invent an exciting dream of her own to gain their approval. Sure enough, they love hearing her dreams as well. Maisie catches on to Annabelle's game quickly, and the two sisters battle it out each day--trying to top one another with the wildest, random and silly dreams to impress their interested parents. But who will come out on top? Maisie or Annabelle?
