If you are expecting a light, frothy romance novel, this is not the book for you. Theo, a veteran of the Crimean War, suffers from PTSD. He retreats to Wales and nurtures a garden in order to escape his horrifying memories and recurring nightmares. While there, he discovers a financial fraud in which his soldiers had been investing unknowingly, and he gives evidence to Scotland Yard that destroys the perpetrator. The criminal's daughter Helena, her privileged life at an end and persecuted by society, flees to live with her cousin in Wales; Theo is their neighbor. Both protagonists have extreme emotional problems, and must come to grips with facing reality and with building a future. The title of the book is interesting, because the word frail has several meanings: physically weak and easily broken (as in emotionally fragile, or in the case of the cousin, ill), a reed basket (the importance of the gardens), the slang English term for a prostitute (weak moral character--Helena considers becoming a man's mistress). While wrenching, the situations in the book are relevant today: the suffering of our veterans with PTSD and the helplessness families experience trying to heal them, the collateral damage heaped on their own families by the actions of criminals, and the healing power of nature.
