Dying Light — Dianne Price

An orphan, raised in an Episcopalian convent, impetuous, outspoken, Jenna Rowan has always had two dreams: to have a family, and to live by the sea. Merrick Hope, an old friend of the Mother Superior, offers Jenna a single solution to both dreams. “Marry my son, Brennan, who is the keeper of the Cape Hope lighthouse.”

Jenna is enthralled by the lighthouse and its breathtaking vistas of the pounding, surging, sea, but the sensory pleasure is dashed by her introduction to the haughty, enigmatic, hot-tempered Brennan Hope. Married life is not at all what she imagined. No husband in her bed, lonely breakfasts and suppers eaten in solitary silence, only the ringing sound of Brennan's footsteps climbing the spiral staircase to the dome -- to the light which must be kept burning -- regardless of someone's sabotage intended to make it fail.

Savage storms, accidents, half-truths, an aura of evil, loneliness, all take a toll on Jenna's determination to hang onto her dreams. Somehow, she must win Brennan's love and help him keep the light burning. But at what cost?
