Angela struggles in the shadow of her more admired older sister. At four, she wants to be a fairy for Halloween and mama obliges with a beautiful costume that includes wings. Cold weather necessitates coats for trick-or-treating, however, and Angela’s costume is partially covered. Older Bernadette wears the coat under her bunny costume and earns raves for her adorableness, while Angela is virtually ignored. The same pattern repeats itself in subsequent years, even when willful Angela tries the same costumes (with minor adjustments) that Bernadette has worn in previous years. Only when Angela comes up with her own costume, which she builds from the ground up, does she lose her resentment and gain a sense of pride. Bernadette comes down with chicken pox, so Angela trick or treats with her friend Albert, remembering to bring back a candy apple for her sister. Wilsdorf’s quirky watercolor-and-ink illustrations add a level of age-appropriate impishness to the tale. A wise and winning story about sisterly rivalry and affection. (Picture book. 4-8)
