Hail to the Chef by Julie Hyzy

Ollie got into the middle of it all again.  She is the Executive Chef for the White House in this very fun culinary mystery.   They are  gearing up for the holiday season and things just start to go wrong.  Some people die, there is a bomb scare, the first lady is being threatened.  It can be intense at times and it just keeps on going.  Ollie aggravates the Secret Service, among others, but ends up being right about many things.  A very fun book and series with great characters and seamless writing.
