How Deep The Roots Go ( Book One) - Michelle Hayes

Born into a mystical bloodline, Temperance Augustine inherited the Second Sight. But with every gift, there is a levy to pay, and the young woman's premonitions are merely attuned to coming evil. Although she can never see the good in human kind, Temperance has not only accepted her fate, but has also learned to embrace it.
When Mardi Gras causes her visions to abruptly stop, Temperance's search for answers leads to the handsome and mysterious Roman. Claiming to be her Guardian, he offers to help Temperance unveil the truth about her powers, but instead starts a chain of events that will make them face the Devil himself. Temperance will need to dig deep within her being to find the strength not only to save herself, but also the one man she is forbidden to love.
