Yes Omega,Never Weak

Gianna Garza is a 17-year-old girl waiting to turn 18 and meet her wolf; normally, this happens at sixteen, but because she is an omega, her change has been delayed. She is the daughter of a beta and an omega who died giving birth to little Gianna, which has caused her father to love her less. Mariano married a beta and had two children: Mariana, who is a year younger than Gianna, and another child who is twelve.
As an omega, Gianna has always been the target of teasing and jokes for being "weak." Because of this, she has trained with her grandparents, who taught her how to use weapons like the bow and sword; they believe that weakness is mental, and that's how she will defend herself. Gianna is in love with Jackson Makris, the Alpha of the Big Silver Moon pack. He is 22 and still doesn't have a mate. He needs a moon for his pack and hates Gianna for being an omega and for supposedly bothering Mariana.
He will detest her even more upon learning that she is his mate and will reject her, humiliating her in front of everyone. Will Gianna be able to find happiness?
