That book you remember the plot of but not the name...

[Yum]

The book I'm looking for is a SciFi/Alien/Futuristic e-book I read a few years ago. Earth woman relocates to a different planet & falls in love with an Alien who used to be a Medical doctor on his planet.

Human woman relocates to another planet after her father dies. She buys a house site unseen,not knowing that the home is actually uninhabitable. The man is a alien in exile from his own home planet. He is a loner, grouchy and initially doesn't want anything to do with her (or anyone.) He's only got one male friend on the planet (the friend is married to a human woman who is not very intelligent but sweet.) The failure of the male alien's arranged marriage resulted with him being charged with a crime, losing his medical license and being exiled to this planet to live out his days. There is a storm and the earth woman has to stay with him instead of going to the home she had bought from him because it was destroyed in the storm. There are a couple of scenes in a local store around the drink sarsaparilla/root beer I think (the store also has a ice cream/soda counter?) The woman really likes the drink and the male alien thinks it tastes like crap and won't drink it, but does make sure they order some to take home. Another scene is where the human female is accosted by another male from the planet who grabs her and disrespects those in the store. The male alien steps in a deals with him. Also, on a trip back from the store, there is a huge storm which delays their being able to safely get back to the house. I think they have to pull over and wait it out for a while. When the human female relocated to the planet she brought with her a jewel her father gave her which, unknown to her, turns out is an energy source for which people will kill her to acquire. (She makes jewlery of some kind or sews stuff with little gems, can't remember ... it's her hobby or side income source.) The alien male's family is a powerful one on his home planet and they make sure he's comfortable on this new planet by making sure he has things from home to keep him comfortable, while working in the background to have the charges against him reversed. He has a big beautiful home and it is self-sustaining given the brutal conditions of the planet. The alien man and his family save her from those who want to kill her for the "jewel" that is the secret to a unlimited energy source. They end up a couple.
