A review by mimosaeyes
The Spy with the Red Balloon by Katherine Locke

4.0

Do you want to read about two Jewish siblings fighting Hitler and each getting their own, well-written queer romance arcs? Do you want a bonkers magic system based on writing equations in blood, mostly on balloons? Then this is the book for you!

I would recommend reading the other book even though this isn't a direct sequel, because you'll like how the world and the minor characters tie together. This book is better than the other, in my opinion, but while I was sceptical at first, I think the author is really on to something with the bizarre-sounding genre of magical historical fiction.
