"I looked at Daisy. Her eyes were glittering and her cheeks were pink. This was Daisy with a Plan. Daisy Wells and Hazel Wong are at Daisy's home, Fallingford, for the holidays. Daisy's glamorous mother is throwing a tea party for her birthday, and the whole family is invited, from eccentric Aunt Saskia to dashing Uncle Felix. But it soon becomes clear that this party isn't about Daisy at all. (Naturally, Daisy is furious.) Then one of their guests falls seriously, mysteriously, fatally ill - and everything points to poison. Suddenly, Fallingford feels like a very dangerous place to be. And when someone close to Daisy looks suspicious, the girls must reveal the truth . . . no matter the consequences."
