Breanna Ban Morna successfully wielded the magic of the Triple Dàns in Destiny Cycle Two, where she removed her father and his fellow Norsemen from the land of Erin, a feat that feat took her life. Her sacrifice forces Danu and Dagda to pull Erin’s Hero into the new timeline, one woven by the young warrior herself and cast over their Emerald Isle by the Heart of Destiny. Yet the threads woven by the Tuatha Gods using Erin’s Cycle of Time to create Breanna’s new life are incomplete. With her mother’s passing, she finds her memories are jumbled. When she discovers she possesses the Heart of Destiny and is indeed Erin’s Hero, Breanna seeks out the Druids at Dun Uisneach to help unravel the mystery of who she is.

After a visit from All-Father, who is now the true Father of Erin’s Hero, Breanna is astonished to learn she is also the new Tuatha Goddess of Time because she wielded the magic of the Triple Dàns. Her new father shows her the fate of Gaels and Celts if she does not accept his challenge to be the one who saves all Gaels and Celts from ruin at the hands of powerful One God-driven dynasties like the Romans and Britons.

 As Breanna builds her small band of warriors and Druids who will make up her Warriors of Destiny, the Tuatha Gods provide them with both weapons of legend and from the future. Using her ability to travel where and when she needs to be, the Goddess of Time sets her sights on Britain, then called Pretannia, six centuries into her past. Could a warrior in ancient times change Ireland's timeline to ensure Gael's will rule? It will take a true Hero and the Tuatha Gods who back her to make that happen!
