Patricia Wrede and Caroline Stevermer's Sorcery and Cecelia, or The Enchanted Chocolate Pot
I was in the mood to read something just straight-up charming, and it had been a long time since i read this one, and it was just great! A really well-done epistolary novel between two cousins in England in 1817--well, an England with magic, anyway. And it's up to the cousins to foil some evil magical schemes--and maybe fall for some eligible dudes in the process. CHARMING.
