I am so sad that this is the end of this series, because Abi truly is an actual genius. As with all the books, this is utterly brilliant. I loved how Zeb is so different to the other kids we've seen before. I also liked that we get a little more of the crossover into the other books, but we still got the time jump. I almost felt sorry for Morg with how long her scheme has been ongoing! Almost ;)

Oonie and Mrs Fickletint were great side characters, and I loved the blind rep too - Oonie was amazing. It was great to see her at home but also somewhere she doesn't know, to see her softer side come out a little.

My only complaint here is not getting to see more of Silvercrag, poor Silvercrag must feel very left out as the only island without a book set in it!

Again we get to see the environmental elements of the writing come to the fore, more so than ever before. While it's nice to imagine that all our issues are because of a magical problem and could be solved, I liked that this kept it magically realistic - there is no simple solution.

I also loved that not only did Zeb come to trust others, but he also came to trust an adult, which was so far from where we see him at the beginning of the book. It was also nice to have an adult along for the ride, makes a change from kids running off alone!

This whole series is just wonderful, and Abi's world-building is so full of imagination. Read it.

4.5 stars.
