I found this one free as well. I don't know how long it will last. But it's the first book in the series.

To find her destiny, she must trust him with her life…and her heart.
Southern Arcana, Book 1
Jackson Holt makes a decent living as a private investigator in New Orleans, home of one of the largest underground supernatural populations in the United States. He and his partners have never met a case they couldn’t crack…until a local bar owner asks him to do a little digging on her newest hire.
New Orleans is the fourth destination in as many months for Mackenzie Brooks, a woman on the run from a deranged stalker. After all, any man who shows up on her doorstep claiming to be her destined lover has more than a few screws loose. But crazy doesn’t explain why he always finds her no matter how far she runs.
When her well-meaning boss puts a PI on her case, Mackenzie comes face to face with the incredible truth: magic is real, and whatever spell has kept her hidden and separate from the paranormal world is rapidly deteriorating.
With time running out, she has no choice but to trust Jackson as he struggles to uncover the truth of her past—and her destiny.

Since the dawn of time, the Light of Epertase has determined when the throne was to be passed from elder to heir. For more than a thousand years, the Light's decision had never been challenged-until now. When a ruthless army advances on Epertase, the Light determines that corrupt King Elijah is no longer fit to rule and his daughter, Princess Alina, is the kingdom's only hope for salvation. When evil men violently abduct her, Epertase's fall appears inevitable. But all is not lost, for Alina has a secret lover lurking in the outer mountains; a long-banished warrior willing to bring down armies and King Elijah himself to save her. His name is Rasi and he prepares for blood. Deadly men plan to sacrifice Alina for the Light of Epertase that lives within her soul. Rasi plans to kill all who try. The kingdom's fate hangs in the balance.
