Always a good read
All of Ms. Heyer's romances are worth reading--and re-reading, too. For quality of writing, characterization, plotting, humor and romance, she can't be bettered. If "Powder and Patch" isn't as good as "The Black Moth" or "These Old Shades" or "Venetia", it's still better than at least 80% of the romance novels by other authors. If you like any of Heyer's novels, go ahead and read it: you'll enjoy it.
