OK – so this is actually Virgin River and this book is where the TV series starts. A mother and her son arrive in the small town, on a wet and windy night and take up an isolated residence. They try to keep to themselves and this is a town where strangers are obvious, but also their need not to socialise is respected. Thus our young mother keeps to herself – as much as she can remembering she has a small son.
As is often the case, when single mothers appear in a small isolated and ‘hidden’ small town, they turn out to be running away from something (trope) – frequently an abusive relationship or a crime they witnessed. And Jack Preacher (ex-military) knows that a split lip and bruises equals abuse. So he finds himself caring for this woman and her child and enables them to hide away – for a while at least.
This is really the start of the series and as such we get introduced to the main characters and their role/s in the township.
