Maude Horton is determined to avenge her sister Constance, who died on board an Arctic exploration disguised as a ship's boy. Questions around Constance's death plague Maude, as does the man who seems to have been responsible for it. Maude ends up getting closer to the man himself, Edison Stowe, armed with her arsenal of apothecary tinctures and medicines, to get the truth and justice for her sister.

I really liked the premise of this book - and I also enjoyed the time setting this was based in, the mid 1800s with a focus on the public fascination with hangings and other public executions. However, I think the overall story and execution of the plot was a bit disappointing - a story of a sister taking revenge on her sibling's murderer should be juicy and tense, and I felt like the story was flat and lacking in these aspects. I didn't really like that we got so much of Edison's POV as it took away from Maude's journey and therefore we didn't get some scenes that could have been really good in her perspective, but got a little run down of why it had happened instead from her when we switched back. The fact Maude is a chemist and knows her tinctures should have been a really big part of the story but it just wasn't, it was so disappointing.

This book didn't quite deliver to me the story I wanted, and unfortunately it's the second time a Lizzie Pook book has done this to me. I think in terms of historical setting and premise, she writes very well but the actual execution of the plot, the building up and connection with the characters always fall short for me. She tends to have really gorgeous covers that don't end up matching the inside of the book.
