Puddin' by Julie Murphy

• Millie Michalchuk has gone to fat camp every summer for as long as she can remember, but this year she's determined to change her life, pursue her dreams, and get the boy (with or without her mom's approval).
• Callie Reyes is your typical pretty and popular queen bee who strives to take her school's dance team to the nationals this year and to become team captain next year (no matter whose toes she steps on along the way).
• When a prank gone wrong throws these two very different girls together, they're surprised to find that they have more in common than anyone would have thought, and their budding friendship shakes up both their lives for the better (but not without some ups and downs along the way).

Although this is a companion to Dumplin' and some of the characters make an appearance (such as Willowdean), it's not necessary to have read Dumplin' to enjoy Puddin' (although it will make a little more sense).  I liked how this book dealt with body-acceptance, stereotypes, and how girls can be supportive rather than competitive (but it never takes on a preachy or lecturing tone).  Also, Texas -- everything just seems more interesting in Texas.
