The series that grabbed me was Deanna Raybourn's Lady Julia Grey Mysteries. I got the first book SILENT IN THE GRAVE on sale from a Bookbub special. She hooked me and I finished the entire series this summer. There are five full-length books and a handful of novellas. The last full-length book hinted at the next adventure, so now that I'm caught up, I'm drumming my fingers impatiently.
I'm a big fan of historicals, and these are Victorian set, taking place mostly in England. (One takes place on a tea plantation in India, which was fascinating.) They are told in first person from Lady Julia's point of view. There is a slow burn romance that I enjoyed throughout the series. These are high in sexual tension with close to zero sex on the page. The mysteries are fun and Lady Julia is a great character. Not perfect, but she has a good heart. Her eccentric family adds another level of high-jinks. And the author's descriptions put the reader in the moment.
If you're looking for a series of historical mysteries, then I highly recommend them! Book 1, SILENT IN THE GRAVE, is still a very reasonable $4.99 in ebook.
What did you binge read this summer? (besides my Cottonbloom series, of course;)
