Vitals is a book about two identical brothers, separately, who are trying to figure out how to make humans immortal. Shortly after Hal Cousins gets a call from his brother Ron, he learns Ron has been killed. Soon, other scientists around the country also studying longevity have been killed. Hal Cousins becomes targeted by those who've used similar research from 70 years ago to keep the secret to themselves.
I finished reading two books, No Time for Goodby and No Safe House by Linwood Barclay. No Time for Goodby is about a woman, Cynthia, when she was 14 years old was caught by her father beyond her curfew drinking with her older boyfriend. The next morning, when she wakes up her mother, father, and older brother are missing. Twenty-five years later she starts receiving messages about where they are. She is now married with an 8 year old daughter and the possibility of finding her family is causing her to act erratically.
No Safe House is a continuation of No Time for Goodbybut seven years later when Cynthia and her family get caught up in a scheme by a local mobster (her boyfriend from when she was 14 years old) who is using other people's houses to hide money, guns, and stolen property in people's attics.
Both novel are excellent reads and, unlike many novels, there are no loose ends or unexplained actions/behaviors.
