If My Sister Were a Worm

AVAILABLE WHEREVER BOOKS ARE SOLD

Holiday House | October 20, 2026

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.

"Sibling resentment turns into a squirmy revenge fantasy in this comical picture book from Hauswirth, making her picture book debut, and Goecke (Billy and The Hole)."

—Publisher's Weekly

"As Maggie’s thoughts spiral, the muted illustrations . . . provide a comical reel of the sisters’ actual and imagined time together, leading Maggie to a wonderfully unexpected conclusion. A light-hearted family story that’s heavy on the laughs."
—Booklist

"...Hauswirth’s particularity makes this iteration memorable: How many kids’ books feature a character who can cure a doll of something called purple-spotted-foot fever? ...Goecke has a lot of pink on her Procreate palette, the better for capturing the fantasized googly-eyed slimy-worm version of Maggie’s irritating sib. An original take on a familiar sibling dynamic."

—Kirkus Reviews

This gently humorous love letter to big sisters doesn’t pull its punches on sources of sibling conflict, but it lingers more on the joys of having and being a sister. . . . This cheeky picture book strikes the perfect balance of humor and sweetness that would fit in just as well at bedtime as it would in a classroom readaloud alongside Barnett’s Rules of the House."
