I read the book years ago sometime between 2009-2011. The book is about this man who was a bastard as he was a result of his father’s affair and treated as an outcast, he inherited his father’s mine his half-siblings didn’t contest it as the mine was seen as useless. In order to gain some respectability he goes to the richest (I think) man in the community and ask to marry his second daughter. The rich man had two daughters of which he loved the second more bec she looked a lot like his late wife and barely acknowledged the existence of the first. The first was thought to be reckless and a gypsy, she had a tattoo of a rose at the top of her left breast I think. She came back with a son less than 7 years. Her father wanting to be rid of her sent for her as she lived somewhere else and married her off to the bastard. The first few months of their marriage was terrible he got mad at her when he came home from visiting the mines for using her money to renovate the rundown house they lived in. They eventually found love more him than her as she had fallen in love with him years ago. Turns out his mine was being sabotaged by someone he trusted this was revealed after he went down into the mines after receiving word that the miners have found gold (I think) unfortunately when he got there he discovered the miners were stuck down there as an explosion which was a constant had happened so he went in there to help and then he realized dynamites had been placed in several places. Not hearing anything from her husband she went to the minefield and met a new buyer and his partner in crime threatening the miners, luckily her husband and the miners were able to come out safely and revealed the truth to everyone gathered. Her little sister was jealous of her and wanted her husband for herself and so she revealed the truth that she was the one who gave birth to the little boy and not her elder sister and he was in fact the father of the boy. In the end he stuck by the elder sister side and kept his son. The story had some sand dunes scenes and the cover was maybe dark red. Thank you
