Collection unavoidable and very well done for children 2 to 8 years depending on the title. My regret: the new version is certainly much stronger, but still takes 2 times more space than before in the library! For book lovers like me who never enough room, it's really an absurd editorial decision. Too bad. I have bought a book in this series since the publication of this release, and again, to replace a lost title. This does not detract from the quality of content, and the ladybug is really a flagship titles and indispensable in the collection.
