This is a cynical series. This is a cynical book. I have to spoil the previous books and small parts of this one, sorry.
The first book tells the story how even though the city is under siege, ingenuity can defend it.
The second book tells the story of how actually, no, the city can't be defended, but ingenuity can save what's important, which is the people, by letting them escape the siege.
In this, the third book ... oh, well, they all died anyway, and the book is about how with ingenuity ... FUCK IT.
Rugpulls are lazy, and multiple rugpulls are lazy as FUCK
I hate myself for enjoying this book, I despise myself for knowing the author was going to do it again yet reading and paying for it just because I wanted to know what happened next.
