CHILDHOOD vaccination may not sound like a compelling subject. But the fall-out from a life-changing outbreak of measles in a small Irish town makes for a thought provoking story about parental choice and responsibility. Emotional and cleverly crafted with welldrawn characters. My Mother’s Shadow – Nikola Scott, Headline Review – out Thursday THE bond between mothers and daughters is at the heart of this delightful family mystery, set partly in 1958. A year after her mum’s sudden death, Addie is shattered when a stranger knocks at her door, claiming to be her twin. As Addie probes her mum’s past, a world of secrets are revealed. Beautifully written and hugely enjoyable.
