"I read this book with satisfaction. It is written efficiently and witty. It discusses the issue of birth in a matter-of-fact, simple and understandable way. Without too much information, but also without blushes of embarrassment. But with charm and a lot of warmth.

The eponymous horror takes place in a child's imagination, fueled by random information, replacing reliable knowledge. I think that the book carries an important message for both young and old readers. Not only about the problem of birth, but also about children's fears. I highly recommend it to all parents."

The book received a literary distinction in the IBBY Book of the Year 2010 competition, was entered on the Treasures List of the Children's Book Museum, and the Polish Bibliotherapeutic Society recommends "Horror!" as helpful reading material when discussing sex education for children over the age of five.
