How Do You Spell G-E-E-K? by Julie Anne Peters
Best friends Kimberly and Ann both have a dream to make it to the National Spelling Bee in Washington, D.C. Eighth grade is the last year they can qualify, so they are practicing day and night. But when Ann is assigned to sponsor geeky new student Lurlene Brueggemeyer, who turns out to be an amazing speller, suddenly her relationship with Kimberly and her chances of winning the competition are put to the test. If the three girls end up competing against each other for the prize, that can spell only one thing... t-r-o-u-b-l-e.
