The Hidden Staircase by Carolyn Keene

4.0

Much more fun than the first book--felt like higher stakes, and the mystery was more solvable for the reader (which always makes it more fun). The new characters were likable, and the villain was fairly creepy and off-putting, which is always a plus. Nancy didn't seem to be quite the golden child she was in the previous book (although she, like Mary Poppins, remains practically perfect in every way).

I was going to give Nancy three books to impress me, so assuming the next one isn't abysmal I guess this is a thing I'm doing now.
