Haunted by Myth by Barbara Ann Wright

Chloe knew her future would be boring. Every job pales in comparison to the family legacy: hunting monsters and banishing ghosts. But that birthright belongs to her mother and sister, leaving Chloe forever outside looking in. Until her sister dies without warning. Chloe gets the family magic, a lack of self-confidence, a grieving mother, a sarcastic spirit guide, and room for nothing else, especially love. And lately, someone seems to be summoning ghosts and protecting monsters, and all clues point to one very famous face: Helen of Troy.

Helen has spent hundreds of years running a sanctuary and rehab for the last mythical creatures on earth. And she has a huge chip on her shoulder about that whole Trojan War thing. Neither she nor Chloe has time for the other's philosophy or to see if their growing attraction is more than skin-deep, not when there are some monsters that won't be sent to the Underworld without a fight.
