This historical fantasy follows two cousins, Kate and Cecy, in a Regency London where magic is real, magicians are everywhere, and some of them aren’t very nice. It all starts with an attempted poisoning via hot chocolate and gets more complicated than either girl expects.

I’ve read this book several times (I own a copy), and I love the characters, the intertwined storylines, and the fact that this story is told entirely in letters between the two cousins. It’s a light, fun read with plenty of action and suspense.
