Titles I've written about:
The Jewels of Sofia Tate (2009):
Think this sounds a whole lot like the opening of a Nancy Drew book? You're not wrong. The heroine is a few years younger, a whole lot more cranky, doesn't have the blue convertible or the confidence—really, Garnet actually doesn't really resemble Nancy at all—but the storyline is very Nancy Drew.
