A super-secret operative saves the world from a diabolical threat through her ability to brandish just the right book at just the right time in this delightfully silly superhero tale illustated by Eisner Award-winner and Caldecott Honoree Vera Brosgol.

When an evil genius has a diabolical plan to destroy every book on the planet, who has the tome-toting page power to thwart his dastardly scheme? 

Lyric McKerrigan, Secret Librarian! She’s got the gadgets. She’s got the disguises. And she’s always got the right book at the right time. It’s a good thing, too, because Lyric McKerrigan is the world’s last hope!

Jacob Sager Weinstein and Vera Brosgol introduce a smart and crafty heroine who is part comic-book hero, part reader extraordinaire, and wholly awesome. 

"Brosgol packs the illustrations with amusing details that add something new to discover with every reading...An exciting escapade with an unlikely hero and a not-so-secret message about the power of books."--Kirkus   "The art is effervescent, with bold lines, bright colors, expressive faces, and several well-placed visual gags to reward attentive readers. Sure to delight budding comic fans, crime fighters, and bibliophiles alike."--School Library Journal   "What if there were a superhero who could give people in trouble the very book they need most? Weinstein (Hyacinth and the Secrets Beneath) spins this winning concept out with cheeky hilarity...Caldecott Honor–winning artist Brosgol (Leave Me Alone!) draws heroes and evildoers with wit."--Publishers Weekly   "Brosgol’s confident line work, vibrant colors, and judicious panel placement allow for the jokes to shine and for the fanciful, energetic plot to move at a thrilling, action-packed pace."--Horn Book Magazine    "The message here: to every reader their book—and what a difference that can make!"--Booklist
