Mabel Opal Pear and the Rules for Spying by Amanda Hosch

Mabel Opal Pear is not your ordinary almost-11-year-old. For one thing, her parents are spies. For another, she's a spy-in-training. She knows immediately that something is wrong when her parents disappear and her Aunt Stella, Uncle Frank, and Cousin Victoria show up. Victoria is mean, Frank is clueless and Stella is something else. Normally Aunt Gertie takes care of Mabel but she's in jail. So it's up to Mabel to not only run the family spoon museum but also figure out the mystery.
I couldn't quite get into Mabel's world. I'm not sure where the connection was missing. It seemed like a serviceable story with some interesting world-building but... not for me.
