This is my first book by the author and I really liked it. This is a group of four women who have been trained as assassins. There are two timelines- brief snippets of  being recruited and trained and then when they reached their retirement age around 60. They are given a cruise to celebrate and things happen that make them realize that a price is on their head from someone in the company that they have worked for.

Each of the four women are so fun. Yes they have been trained as assassins but they are also so very clever in their own rights. It is just non-stop action from beginning to end and I highly enjoyed it.
