Seeking: Warrior Mate

Clean, short fantasy romance. Ari the Noble, a rare female Aasguard warrior, loses her dragon to old age. While mourning she seeks the comfort of her brothers, fellow Aasguard warriors. Both of her brothers have recently married-unheard of among their kind. This has given birth to thoughts of a life she never envisioned for herself. These thoughts only multiply after she meets Kellen the Mighty. Kellen the Mighty's dragon also succumbed to old age and now he's struggling with echoing loneliness.
This propels him to seek out other Aasguards and investigate the possibility of marriage for himself. Both Ari and Kellen struggle with their returning emotions and feelings for the other that they've never encountered in their long years of living. When they surrender to their mutual attraction, a portal opens to a monstrous creation that immediately and gleefully attacks. Could this catastrophe mean the end of their union? As well as the unions of future Aasguard warriors?
