And try I have. Nine books since the beginning of the year. Fortunately, Heyer wrote more than 50, so I should be good for awhile yet.
She wrote from the 1920's to the 1960's and is called the "Queen of Regency Romance." She's often put in the romance section at stores and libraries, but the "romance" in these books is on par with the romance in Jane Austen novels. It's there, but it's only slightly central to the plot.
What it comes down to is that Heyer is a fantastic writer with keen insight to the ridiculousness of people in general. Her plots are never the same--even while the set-up often is--and the twists and turns are both unexpected and delightful.
Some of my favorite so far: Friday's Child, The Quiet Gentleman, The Foundling, Black Sheep, and The Masqueraders. Try one, they are deliciously fun!
