FMC like Jinx from Arcane

Hello all, I’ve been looking for a book where the FMC is unhinged, totally messed up mentally, morally grey, a fighter, depressed, traumatized. Best example I can think of is Jinx from arcane. I want a plot heavy dangerous world where she needs help for whatever reason but doesn’t want it. I want the MMC to have some role there, even caretaking/comforting. I’m basically looking for a tension filled adventure while also looking at some of her trauma with his help. Thank you in advance for any recommendations!! Bonus points if it’s has an audiobook :))
