Besides successfully explaining the scientific method, and what we've come to call the placebo effect, author and artist give children insight into human behavior--with a large dose of humor. For history buffs, science enthusiasts, and fans of a good story, this one hits all the marks.
--Shelf Awareness (starred review)

This ingenious book celebrates -- and explains to children clearly -- the basic principles of the scientific method, while also doubling as a peek into the astounding life of Benjamin Franklin.
--The New York Times

Rockliff's text is engaging and lively and pairs beautifully with Bruno's dramatic and bold illustrations, which fully conduct the audience's attention. There is no way a reader will escape the truly mesmerizing and energetic design.
--The Horn Book

Bruno's digitally colored pencil art lightly evokes period caricature and gently pokes fun at the ornate clothing and hair of French nobility. The tale is nicely pitched to emphasize the importance of a hypothesis, testing and verification, and several inset text boxes are used to explain these scientific tools. Rockliff points out that Franklin's blind-test technique is in use today for medical treatments, and both the placebo effect and hypnosis are studied today. Rockliff and Bruno's playful approach buoys solid science and history.
--Kirkus

"Mesmerized" has so much page-turning suspense that it feels ripe for adaptation and box office success.... Although the book sounds heavy with facts and theories, the story zips along thanks to Mara Rockliff's lively, dramatic writing that holds even young readers in its thrall. Iacopo Bruno's illustrations are stylishly elaborate, shown from shifting perspectives. And the pages are cleverly laid out to accommodate short bursts of information. It's not typical picture book problem, but this story might be just too thrilling for bedtime.

Rockliff retells the episode with equal measures of gentle satire of aristocratic gullibility and tidy re- construction of the scientific method.
