Morning Star (Starlight Trilogy #3) by Marian Wells

Out of her dark childhood memories, her fascination with the spirit world and her conversion to Mormonism, Jenny has been slowly but surely groping toward spiritual light and truth. Her young husband Mark has gone through his own sometimes painful spiritual journey and been soundly converted to Christ. His faithful witness, more through his life than actual words, brings Jenny to the choice which helps to break the chains of spiritual bondage and bring her to the feet of the only true "Morning Star," Jesus himself.
