I thought the book was very cute, though I must admit I loved the illustrations more than the text. I absolutely love Delphine Durand's illustrations!
The story is cute, and the topic of "Snoops" is one that's funny and not overdone. But something about the text: the word choices, meter, etc., was a bit awkward to me. I couldn't tell whether this book was supposed to rhyme or not. It certainly seemed like it was intended to rhyme (in the sense that the word choices were sometimes very awkward), but it did not rhyme. Perhaps it was written in another language besides English, and translated without rhyme? That would explain things.
Overall, I'd still very much recommend the book.
