I love these books. Amanda Quick does, in my opinion, the best historical romances with a touch of mystery. I appreciate the mysteries because it gives the story some bite, beyond just plain romance.
In this one, we enter into a bit of a crossover situation. The author has a series under the name Jayne Castle, which are futuristic and paranormal. This book is a historical romance but part of a series with paranormal aspects.
In this case, Lucinda Bromley is a gifted (psychically gifted) botantist and has recognized a rare fern that was stolen from her conservatory in a deadly poison. She teams up with Caleb Jones, who runs the detective agency for the psychical society and they track the poisoner, who is well known to the psychical society for various other unpleasant crimes.
It appears as though he is trying to create the “founder’s formula” which is a potion that should enhance and increase the psychical abilities of the person who takes it. Unfortunately the problem is that the founders formula, in every iteration, works briefly and then works as a poison, driving people crazy before killing them.
So it’s a bit of a race against time. The poison creator is working for some richer men, who are using their psychic powers to kill people and as they get more crazy from the formula, they will become exponentially more dangerous.
Meanwhile, sparks are flying between Lucinda and Caleb.
This is an enjoyable book. I recommend it.
