Mortal Enemy Mates

Michael is a powerful Black Panther, destined to take over the pride and rule along his mates side when the time is right.
Kiera is the most powerful wolf there is, and she is the alphas daughter, competing with her twin brother, Caleb for the throne.
There's just a couple problems:
1. Michael and Keira are mates, as they find out in the middle of a hectic battle.
2. Wolves and Panthers have been at war with each other for years. What they don't know is deep deep down in in a prophecy that was never taught or even looked at...
The prophecy states: there will be one wolf and one panther fated together forever. MATES. They will unite the cat and wolf kind and kind the senseless killing and battles bringing them towards extinction
