Kitty and Jeff have been enjoying a relatively quiet few months. Kitty is working with some of her friends to expose the Mastermind, but they haven't had much luck finding the evidence they need, and just when it appears life has settled, an assassin who looks a lot like Jeff's niece, Stephanie, appears. Then the Alpha Centauri Planetary Council requests a visit to Earth wanting to meet the president and vice-president. The villains captured in ALIEN SEPARATION manage to escape from the secure prison complicating life even more. Next, the president dies after exposure to what everyone assumed was a mild virus.

The virus starts taking even more lives as Kitty and Jeff find themselves being sworn in as the President and First Lady. As they battle their enemies, Kitty finds herself guarding a young lady who is the daughter of one of Kitty's assassin friends. When everything goes sour, it's Kitty's quick thinking that will save their lives as well as many others.

Ms. Koch's highly successful Katherine "Kitty" Katt series just keeps getting better with ALIEN IN CHIEF. Ms. Koch does an incredible job of world building. She keeps the tension high in each book, and her writing keeps the reader hanging on for the ride. I love Kitty's attitude in general but especially towards those who hurt her friends and family. She is unforgiving when the need arises. The love story between Jeff and Kitty became a smaller part of the story in ALIEN IN CHIEF, but it is a pivotal part of what keeps the reader invested in the stories.
