Witch Blood (Elemental Witches, #2)

Only lust burns hotter than revenge...A water witch, Isabelle Novak has always led a chaotic, nomadic existence. But her life spins out of control when her sister—her only friend and emotional anchor—is killed by a demon. Driven by grief and a desire for revenge, she turns her back on the Coven and its sacred rede: Harm ye none...When Isabelle first encounters Thomas Monahan, she's running on pure rage and sorrow, channeling her pain into power—and trying to freeze the life out of a warlock she holds responsible for her sister's death. Together, she and Thomas form an uneasy alliance to hunt and destroy a demon of tremendous power. As head of the Coven, earth witch Thomas must thwart Isabelle's dark impulses, but his very presence stirs deeper desires she never knew she had.
