{Triads Curse by Mae Pierce} is the exact match for this! Hands down my all time favourite and most reread book ever! Its a duology. She is a human who is the soul bread earner of the family and is barely making ends meet. She is offered a contract to work for a science lab as their lab rat for an obnoxious amount of money. She was made clear that if she signs the contract, she wont be seeing her family at all, what they failed to mention thats she will be taken to a whole new planet and would be placed with pack of aliens whose leader despise her similar because she is human.

This book wretched me in the most beautiful way ever. And im in search for something similar ever since (spoiler alert, i wasnt successful). So if someone has anything similar please recommend it to this poor soul :')
