A brilliant ending for this trilogy. Full of twists and turns that I did not see coming. We finally learn how the Scholomance came about.
The book explores themes such as balance, destiny, friendship and fairness

It's been a while since I read book 2 in the series and I contemplated re-reading before picking this volume up because when I initially tried to read it I was overwhelmed.  Book 2 leaves on a cliffhanger and book 3 starts right after and so you see the immediate events and it was a little difficult to jump right it.

I thought that the series was quite solid.  Book 3 really tied it all together and bits that were resolved were introduced in book 1 so it was quite good closure to see actions that have consequences and a resolution all together.

Some of the reveals were also top notch, since there's (in hindsight) a lot of foreshadowing but to be able to put it all together wasn't something I managed.  I don't know if it was because of the gap between the books and it would have been obvious if I read them in closer succession but I was satisfied with how it came together.
