    A pitch-perfect tale of sibling strife and over-the-top antics in the vein of Alexander and the Terrible, Horrible, No Good, Very Bad Day.

    What do you do when your sister steals your thunder? You turn her into a worm, of course.  

    Worms don’t pop your birthday balloons. They don’t “help” you open your presents or prematurely blow out your candles. They don’t steal your favorite seat on the school bus! 

    On the other hand, worms can’t play with you before bath time. They can’t be your sidekick at family weddings, and they definitely can’t make s’mores with you at summer camp. Plus, they’re REALLY easy to lose. 

    If Maggie isn't able to turn her sister back into a human, she’s in for a lifetime of parental blame and worm-hunting. There may be only one thing left to do... Are two worms better than one? 

    This hilarious picture book captures the bond between sisters—the good, the bad, and the worm-y—with deadpan humor and surprising warmth. The perfect read for anyone who has to share the spotlight with a sibling
