The third installment in the series by Hilary McKay about the hilarious Casson family. There is a great part about a chocolate cake/swamp. So that's why you really don't want to miss this one.
It moved the Casson's story right along, and I'm looking forward to Caddy Ever After -- I think it will be more fun and less . . . disturbing (though the Cassons are charming as ever in this one and you get to know blundering David).
