Day 3 of #AdventRecommends - this book was on my TBR for about 3 years before I read this!
Juliana is interested in science and ladybugs. She gets sent to London and secretly works on her research. She meets Spencer who works as a spy in the war office. They work together and obviously fall in love. It‘s a YA Historical Romance, so you kind of have to know what you‘re in for.
