In this fun and honest romp about friendship, puberty, and growing up, a debut author gives modern-day readers their own version of Are You There God? It's Me Margaret, for fans of Pixar's Turning Red.

Twelve-year-old Tahlia Wilkins is ready to kick off the perfect summer, starting with an invitation to a pool party being thrown by the most popular kid in school. But when the Red Goddess of Panties, aka her first period, arrives twenty-four hours before the party, it messes up all her plans. To make matters worse, her mom is out of town, and there’s no way she’s going to ask her awkward dad for help! Tahlia always feared that growing up would be tough, but this is just not fair.

In order to save herself from total embarrassment, it will take all of Tahlia and her best friend Lily’s scheming to keep her reputation—and her favorite jeans—from being ruined. Sneak off to the grocery store only to have the clerk price-check your tampons over the loudspeaker? Check. Trick your mature teenage neighbor into letting you use some of her tampons? Check. Take a dip into a fountain to get quarters for a bathroom period product dispenser? Check, check, check!

With the hilarious and heartwarming tone of Dork Diaries, Grow Up, Tahlia Wilkins! is a coming-of-age middle-grade novel about growing up, in all of its awkward glory.
