Mystery has always surrounded twelve-year-old Juniper's beloved great-grandma, June. Born in rural Wales, or so everyone thought, how did she come to live in California? How had she met Juniper's great-grandpa? And why, despite her age, does she never mention World War 2? But when June develops dementia, she determines to tell Juniper her astonishing story before it is too late. Recording every word, Juniper finds herself immersed in the exhilarating and dangerous world her great-grandma knew as an evacuee on an isolated Welsh farm. Her tale of escaped prisoners of war and swanky American soldiers, of unlikely friendships and first loves, brings history alive for Juniper as she discovers her June's incredible past – an evergreen past that is about to arrive in the present!
