The Half Brother by Christine Keighery is a bit like a car crash. Not in the sense it’s bad. More in the sense that you can see what’s coming but are powerless to stop it. Keighery puts us in the heads of sisters Hannah and Stef – dissimilar but close when we first meet them – and their half-brother Alex… who we learn from the outset has quite a dastardly agenda which means Keighery is able to create a sense of menace that oscillates throughout the novel.
