SOLVED. Adult Shifter Romance: The Alpha's mate died and he leaves the pack to grieve. The FMC, who cannot shift, is sent to convince him to come back.

- Plot: Alpha's mate died (best friend of the heroine) and he left the pack to go grieve in a cabin in the mountains. He is semi-wild and the pack needs him to come back because war is coming to them and he is a very strong alpha.
The heroine is a pack member who cannot shift although I think she is in her mid-late twenties, so they send her because she is a bit expendable. Importantly, she is sleeping with the alpha's best friend, who doesn't want to mate her because of the fact that she cannot shift.
She goes to the mountain, he doesn't kill her but starts ignoring her, and she cannot leave in good conscience. She stays to take care of him since he is living in filth and is very emanciated I think. He gives her an ultimatum that he thinks is impossible: He will only leave the cabin as her mate,and only if she shifts. She agrees, but fails to shift until they are attacked by assasins trying to kill him and she manages to fight as a wolf in the fight.
They leave the cabin as mates and return to the pack. Her old lover now confesses his love and tries to mate her since she now managed to shift, but she is loyal to he new unlikely mate and refuses. The rest of the book is them getting closer and preparing for war.
