This is the second of, what I hope to be, a long series starring the daughter of Sanford’s best known hero. She is in her 20’s, smart, pretty, and knows how to shoot. She works undercover for Homeland Security. In this plot, taken from the headlines about Russia’s invasion, she is sent to infiltrate a group of hackers. There is plenty of action, and we get to meet new, hopefully recurring, characters. My only criticism is there is generally a lack of “snappy repartee”. There is more humor in the Lucas Davenport series. All in all, Letty is a well written character. And I eagerly await the next in the series.
