Raybourn writes historical fiction with a twist; she's best known for her Lady Julia Grey mysteries. This is her first novel in a new Victorian series featuring the badass but well-bred Veronica Speedwell. I heard the author speak about her source material for this new series in Raleigh, and I was intrigued: her heroine travels the world hunting beautiful butterfly specimens and the occasional romantic dalliance. When her guardian dies, the orphaned Veronica expects to embark on a grand scientific adventure. But Veronica quickly realizes that with her guardian's death, she is no longer safe—and she begins to unravel the mystery of why she poses a threat to dangerous men. An easy, enjoyable read.
