War Paint — Sandra Byrd

Book Six: War Paint Should she compete in an all-out mural painting contest with her Secret Sister, Erin--or run for "Miss Coronado"?
Tess must decide!

Competition is fierce for the sixth grade mural team, and Tess's Secret Sister, Erin, desperately wants their group to win. Tess is determined that they will, despite a threat of "war" from members of the snobbish Coronado Club, who have decided they deserve to paint the mural.

Tess is shocked, however, to learn that she's one of four girls nominated for the "Miss Coronado" contest. If she decides to run, she has to drop out of the mural competition--perhaps ruining her team's, and Erin's, chances. If she doesn't, the catty Lauren is sure to become "Miss Coronado." And nobody, not even Erin, wants that. What will Tess choose?
