I read the comics first, but the library FINALLY ordered this series. And...
Pretty much like a regular Thea Stilton book. Canonical throughout most of it for the most part, but changing names of some recognizable side characters. For example, Vanilla de Vissen in the comics= Ruby Flashyfur in the books. I don't really mind that, though I wish everyone and all relationships were the same in the entire franchise.
Only part that I didn't like was the difference in pairing of Pam and Ruby's brother, Ryder. In the comics, they had this great back and forth relationship, but they have no connection in the book. THAT DRIVES ME NUTS. I wanted to read this series to see more of their relationship, but I'm being forcefully nudged to wanted Ryder and Paulina together. All together from all the franchise's properties, Paulina has at least 3 love interests. I definitely don't ship this.
Yeah, so I'm a bit (really) old to read this series and be so riled up about it, but I gotta say what I gotta say. This was a good book, but unfortunetly, it didn't give me the one thing I wanted the most: canonical confirmation of a ship they had previously imagined.
