Sisters Three — Jessica Stirling

There are four Conway women: indomitable Lizzie, who endures despite everythign that life in Glasgow can throw at her, and Lizzie's three daughters, each one combining Lizzie's iron will with her own ambitions and desires.

Now, as the 1930s draw to a close and war threatens, each sister struggles with her life and loves. Polly lives in luxury as the wife of the overprotective Dominic Manone, while Babs has her hands full with her demanding brood and her fast-talking husband. Only Rosie seems to have found peace in Shelby's Bookshop...until a young policeman comes around.
While Polly seeks distraction in a dangerous affair, her husband is drawn into a venture involving a sinister go-between, a beautiful and amoral blond, and an unimaginable fortune.
As the web of suspicion and deceit tightens around Dominic, Polly finds herself threatened from all sides until she is finally forced to make difficult choices about her sisters, her husband, and her own unfulfilled desires.
