The Rainbow Years (English, Paperback, Rita Bradshaw)

Born during World War 1, Amy Shawe gets off to a bad start as her unmarried mother dies in the 1919 flu epidemic and Amy is only spared the workhouse because her uncle grudgingly takes her in. Her cousin torments her as she grows up and when she gets the chance to marry a rather older and apparently loving man she seizes the chance to escape what is becoming a dangerous situation. Tragically she’s gone from the frying pan into the fire and endures some difficult years with a violent husband, made bearable only by the arrival of a baby. When tragedy strikes, she joins the WAAF at the start of WWII; in her new life she keeps her marriage a secret and eventually falls in love with a Spitfire pilot, Nick. Her chance of happiness with him seems to be blighted, though, when fate compels her to care for her now ailing husband: but her suffering has not, in the end, been in vain, and Nick will be waiting when the time is right.
