Not by Blood is a standalone debut thriller by author, Chris Narozny. A story of childhood trauma, family relationships and the questions we ask about how well we really know those who are our ‘blood’. Tina and her biological brother, Bill faced in childhood something that no child should have to. Their father was convicted of murdering their mother and Tina was sent to live with a foster family and Bill, a group home. Years later, Tina’s search to find her missing brother might uncover more than she bargained for. This one was a quick read and the pace fast moving. The story took a little bit to set up all the characters, layers and backstory but then what unfolded was a gripping ride to the end as the author peeled back layer after layer until the very end leaving me shook. I enjoyed this chilling family mystery and would read more by this author.
