A Touch of Magic - Rita Boucher

A mage without power. A witch without hope.
Desperation drives the beautiful, widowed witch, Genevieve Dale, to seek the help of Etienne, the notorious Comte du La Fey. Exiled to England, cursed for violating Merlin's laws, Etienne must live a life without magic unless he can somehow redeem himself. Ironically, the disgraced mage is the best hope of Genevieve's son, Louis. Other than Etienne, no one is willing to mentor the half-Outsider boy and help him learn control of his dangerous magic.
Etienne soon finds himself wanting far more than the fake betrothal that is part of his bargain with Genevieve. Only her touch can calm the turmoil of the roiling power suppressed within him. With their futures at stake, Etienne must choose between the possibility that he can break the curse or take the chance that he might lose his magic to gain a lifetime of love.
