An Omega's Shadowed Path

In the ancient times, Ashwind Airtoss has lived most of her life in the Werewolf's Half Moon pack, only an Omega, but well-fed, well-rested and treated well, she never wanted for a different life, but was content.
Well, perhaps she would like to become a chosen for the kingdom, be a royal secret soldier for the Alpha King. So she waited for the summons every year.
But then she discovered the dark secret of Half Moon's Alpha, and she needs to carry out the warning that will crush the kingdom and its inhabitants.
But the risks are not small.
If she fails the running spree granted her from exhaustion, she may never awake from another sleep, and if she does, she will not remember her past.
If she survives she may never again be able to shift into a human.
If the worst comes to the worst, she may die, and only two small sheets may be found to bring the incomplete warning to the King. . .unless the rogue Alpha's wolves find her first.
