★★★½
I have a mixed relationship with the author Mary Gentle, having now read two of her books: Ilario, long before I started this blog, and Black Opera some years ago. 1610 has been sitting on my shelf for over a year and, in the course of a warm, sunny weekend, I decided to give it a go. A sexual assault in the first few chapters gave me pause, but I pressed on regardless and soon found myself in the midst of a very enjoyable swashbuckler, populated with spies, rogues, kings, mathematicians and cross-dressing swordsmen – and taking in the France of Marie de’ Medici, the England of James I and, unexpectedly, Japan in the years before the Sukoku Edict closed its borders. I should stress that this isn’t a fantasy, but a rollicking historical adventure with a few hints of the mystical: best described, perhaps, as The Three Musketeers with added esoterica.
