Georgette Heyer is worth being lazy for.
Heyer was an English writer of romance and mystery novels. She was born in 1902, died in 1974, and wrote from the 20's until her death. There are not many authors who give me more pure, unalloyed pleasure than Heyer. I didn't think I could possibly enjoy romance novels until I read Heyer (and I have read many romance novels since trying to discover books I will like even half as much as hers . . . to absolutely no avail. Other than Austen, I like literally no other romance authors.)
Her romances are almost all Regencies (set between 1811 and 1820), though a good handful of them are set thirty years earlier than that. Her thrillers are generally contemporary to when she was writing them, though some are also set in the Regency or Georgian periods. She more or less single-handedly created the modern genre of the "Regency Romance," but no one afterwards has at all equaled her.
What I find so delightful about her is her sense of the ridiculous. She knows exactly when to lead us along with a ridiculous plot (almost always) but also when and how to make fun of it (again, almost always).
