Silly and charming, but not as silly or charming as the first. The letter game format worked really well when Cecelia and Kate were actually writing to each other, but when they're on the same trip, writing about basically the same events, the plot drags a little. Also, this might seem like a small quibble, but the choice to have Kate writing in a diary and Cecelia in a formal deposition seems to immediately set the reader up to favor Kate and Thomas (honeymoon! romance! obviously implied sex!) over Cecelia and James (this happened and then this happened and then this happened), which was a bummer. I'll be reading the third, but my hopes aren't too high.
