Half A Heart
"I, Grayson Dolan, reject you, Amber Sparks, as my mate and future Luna of the Chrystal Moon pack."
"I, Ethan Dolan, accept you, Amber Sparks, as my mate and future Luna of the Chrystal Moon Pack."
I know what you are thinking, how? We'll meet Amber your average girl. And then meet Grayson and Ethan identical twins, who happen to be in line as the next alphas.
Twins usually have the same mate, so what happens when one twin rejects them, while the other one accepts them.
