2 Tails and Counting - Kora Kari

Misha did the last thing a spirit fox should do. To save a dying human child, she gave him her fox bead, binding her soul to his for eternity. For decades she has guarded him in secret, protecting both the boy and the bead he holds.
But a sly red fox demon has his eyes on ruling the northern clans, and he needs Misha by his side to do it. If he can claim her as his mate before her third tail grows, her lineage and her power will become his.
Now Misha must outwit a fox who plays by no rules, while protecting the human she is bound to.

"Power grows with each tail... but so does the danger."
