Waiting for my Mate

Writing Prompt from my friend:

Sara leaves Germany to travel around the world, when she arrives in Presque Isle, Maine the Abenki tribe wolves attack her. Saved by Garrett of the pack, he wants her to stay in Presque Isle because he believes a descendent will imprint on her. After saving her life she has no choice but to agree to his simple plead of staying here for an unknown amount of time.

She waits for half a century to finally get to meet the love of her life, but when he doesn't imprint on her like he should she is rejected from her assumed mate with force. She leaves her family to continue her travels around the world, but while no one is the wiser, will she fall for someone else or will her mate agree to take her? Will war bring her back home or will it push her further away?
