Awakening rejected Mate

Alora Dennison is an orphaned child from a shamed bloodline surviving in her families old pack. On the dawn of her transition pushing her into adulthood she imprints on the mate she will be bonded to for an eternity, in an unexpected turn of fate.
Only he isn't the man of her dreams. He is the only one in the entire state she would never have wanted to bond too.
Colton Santo is the arrogant, dominant son of the Alpha from a rival pack which is set to unite the packs and reign in one kingdom. In years gone by his disdain for her and any from her bloodline has been prominent. Her treatment by his pack has pushed her to live in near isolation, fearful for her existence and now before all assembled, on the dawn of her awakening, they all just saw her imprint on their future leader.
Fate has decreed it, but everyone around her is about to try and stop it.
Fate isn't about to make it easy on her either, as a long forgotten war erupts in their lands, bringing an age old enemy with a thirst for blood back into the forefront of lycanthrope life.
Will she survive long enough to ever find out why she has borne a black mark on her lineage her entire life? And why exactly, Colton's father is just so eager to see her dead.
Will Colton step up and honour the bond, or will he be the one to deliver the final blow?
