Duke seeks bride / Christy Carlyle.

"Miss Evelyn Graves has never had a holiday. She is much too busy as the personal secretary to the Countess of Waverly. But the Duke of Ballymore Castle in Connemara, Ireland, has invited the countess to visit—and as the countess cannot travel, she has insisted Evelyn go in her stead. Except when Evie arrives, everyone mistakes her for the countess—and it’s clear the family who owns crumbling Ballymore were hoping to match the widowed countess with Alexander Pierpont, Duke of Rennick. Though Alex knows the truth of Evie’s identity, he has an unusual request. He’ll happily show her hospitality if she’ll agree to let others think she’s the countess during her visit. There’s just one problem: as time runs out on their arrangement and Alex increasingly fears he must in fact marry an heiress to save his family’s fortunes, he finds that his heart now belongs to Miss Evie Graves…and he can’t bring himself to let her go" --
