Minding the Light, Nantucket Legacy Series by Suzanne Woods Fisher and published by Revell.
Six long years ago, Captain Reynolds Macy sailed away from his bride, looking forward to the day when he would return to Nantucket Island with a ship's hold full of whale oil. But when that momentous day finally arrives, Ren soon discovers that everything has changed in his absence. Everything. "Is nothing on this island as it appears to be?" he whispers in despair.
Unlike most islanders, bold and spirited Daphne Coffin doesn't defer to Ren as an authoritative whalemaster, but sees through his aloofness to the aching heart beneath. She encourages him to return to his Quaker roots and "mind the Light," finding solace in God and community. As Ren becomes the man she believes him to be - honorable, wise, faithful - she finds herself falling in love with him.
But how can she, when her heart is spoken for? Tristram Macy is Ren's business partner, cousin, and best friend - and Daphne's fianci. Love always comes at a cost, but when is the price too high?
