What's the Name of That Book??? discussion

Ok I remember the first part of this book pretty clearly. The mmc is a captain of a large war ship(maybe of many ships but is the main leader of it) and he comes to earth because another species of alien has invaded it. His younger brother sneaks out to the front lines and gets badly wounded. He hide in an ally where the fmc finds him and drags him to her shelter which is basement of a building that is hidden, before the aliens that are looking for him can find him. They can’t understand each other when the brother wakes up but she wraps his wounds and feeds him. Her food is running out so she grabs an empty backpack and leaves her shelter to find more food. She finds a hidden store or storage that hadn’t been looted yet and packs her bag as full as she can before she hides the entrance and goes back home. She gives the brother either canned tuna or canned chicken and he doesn’t care for it but still eats it as he is hungry.
The mmc learns his brother is missing and demands that he is found immediately or else.
The fmc is running out of food again, the mmc brother eats a lot, so she goes back to the store she found before and fills her bag again. I can’t remember if she made it back to her home or she gets stopped on the way but the mmcs people find her and the brother and she gets injured bad when they arrive and the brother demands that she gets taken back to the ship with him to get healed. When she wakes up from being healed she learns she is no where near earth anymore and she meets the mmc
I also am 50% sure she is fate mate to the mmc but that could just be cause I’m reading a ton of shifter books.

These are longshots, but they have similar plots in them to what you're looking for. Garrison earth series by v.k. ludwig and some of S.e. smiths books.
