Rejected But Wanted By The Alpha King

Rashel, an overly supportive wife and Luna to Alpha Seth, who helped her husband build his pack to become the envy of all, thought her life was finally about to take the best turn she had always hoped for. But nothing prepared her for the fall from grace to grass fate had for her.
It is tradition that any Alpha without an heir at age 35 would lose his pack to the next best contender. And in this case, Alpha Seth's younger brother, who was an arch enemy, was the next best available contender, and he was willing to do just anything to make sure his brother, Seth, lost the pack to him.
Disgraced and forced out of her pack after her husband found out he had a second fated mate, Rashel left with the one thing Seth needed to retain his pack – Her pregnancy.
She was given a second fated mate, who turned out to be the Alpha King, Jethro. The one man who held the entire werewolf nation in his palm.
Rashel thought that life had given her and her baby a second chance, since Alpha Jethro loved her to the moon and back. But what she didn't know was that her misery had only just begun, because not only did Seth regret letting her go, but now he desperately needed her and his child—the heir to his pack—back in his life. But this would be over Alpha Jethro's dead body.
Rashel is caught in the middle of an impending war between the man she once loved and the man with whom she gradually built a new life.
Now, she has to find out where her heart truly lies and whom she wants to spend the rest of her life with.
