I used to be really into Elaine Viets, but her books started reading as really formulaic to me, and one of her heroines (I forget which one) made a series of startlingly foolish decisions in one of the books, so I've given up. I don't think you missed anything.

The thing with What Did You Eat Yesterday is that you don't need to read the recipes/food prep portions if you don't want to. Her characters and their situations are just so well observed that I keep coming back for more. :)
