I completely loved this book! Alvie is adorably awkward, and Bennett is just adorable. I cannot wait for more books by Charlie! I really loved the first three books in this series, but this story was something special. I hope the author does more in this world!

I have to admit, I enjoyed this instalment the most out of all the books in the series thus far.

Alvie was such a great character and I found her so much easier to connect and relate to than the character of Ceony in the other books.
Ceony seemed to mostly annoy and frustrate me, whereas Alvie was delightful!
She’s smart (like, really really smart), clumsy, bold, adventurous, hardworking, plucky, brave, curious, and most of all - she really REALLY likes to wear trousers *gasp*!
I loved that she was a little bit different and didn’t really care what people thought about her.
She was wonderful.

I also enjoyed being able to take a break from paper magic and folding for a while (though there is a sweet little cameo appearance hidden in here which was lovely).
I found Polymaking and plastic magic to be fascinating and it was refreshing to learn about something so completely different from the paper magic we’ve had in the other books.
The Polymaking gave this book more of a sciencey edge and almost gave it a kind of steampunk vibe somehow.

The story was also lovely, if a little obvious and predictable.
It’s a lovely little adventure to carry you away for a few hours, just don’t expect any Earth-shattering plot twists along the way.

All in all this was a very enjoyable book and I’m looking forward to seeing what Alvie gets up to next!
