From the mailbag: "HarperCollins is estimating that Jessica Seinfeld's book [about tricking kids into eating healthy by pureeing their veggies] Deceptively Delicious has sold ~125,000 in its first week on sale. This week's sign of the apocalypse: that a woman with no discernible talent other than dumping her fiance when a richer guy comes along has just had what's arguably the nonfiction debut of the year. There's something like another 250K on order."
