Genre: Historical Short Novella
Publisher: Ellora's Cave
If you've had a rough day and want an hour's diversion, "Gambler" by Eryn Blackwell might be your answer. (Full disclosure: I read it in 47 minutes.) This short novella doesn't waste time with plot, creative dialog or developed characters, but gets right to the heart of what Ellora's Cave aficionados expect: abundant and explicit sex.
While the manuscript could have benefitted by an editor's firm hand, the goal is still accomplished. As for the setting being historical - the only bit that plays is in the initial set-up of the scenario; otherwise, the story could be anywhere anytime.
*Note: The Ellora's Cave website does mention that this story was previously published elsewhere.*
