Challenged by Fate

How do you find and kill a Goddess when she can go anywhere?
Ariana’s world is turned upside down. She thought the curse was almost finished. But time is running out for her to bond with all her mates, and she is missing one. Gray is in the clutches of Rowena, the goddess who calls herself Fate. She issued a challenge for them, one they will have to answer as Ariana and the guy's race to find him. Problem is… He’s no longer in their century! How do you find someone who could literally be anywhere in time and space?
When it’s all said and done, who will save who?
Can they defeat Rowena or will she prove to be too strong? Will Ariana and her guys succeed in time before the curse kills her? Or will she end up leaving her daughters to grow up without their mother?
