A Sense of Fate by Wendy Soliman

Flora Latimer settles into life as an independent young woman in Lyneham village with Remus, her interfering spirit guide, always willing to offer unhelpful advice. She spends her days helping the infirm with her herbal remedies and furthers her friendship with Archie Hardwick, the injured Marquess of Felsham, who is now a close neighbour.
Returning to Salisbury for her sister’s wedding, Flora despairs when her father, the Cathedral’s Dean, attempts to encourage her interest in Elroy Conrad. Flora makes her dislike in the flamboyant banker plain but Conrad proves to be annoyingly persistent.
Flora’s routine is turned on its head when Melanie, her youngest sister, arrives at her cottage distraught and badly beaten, begging for sanctuary. Flora recognises the nature of her injuries, having herself suffered similar brutal punishments at their father’s hands.
Flora fends off her father’s demand for Melanie’s return, and struggles to repel Conrad’s unwelcome attentions. Flora and Archie, at a loss to understand Latimer’s connection to Conrad, delve deeper and uncover a shocking secret. Before they can decide how to act on it, Melanie’s life comes under threat. Given warning by Remus, Flora doesn’t hesitate to rush to her sister’s aid without stopping to consider the consequences.
Will Archie’s disability prevent him from saving the woman who has come to mean so much to him from her own headstrong determination…
