The Duke's Christmas Fake Fianc?e — Sophia Williams

A festive friends-to-lovers Regency romance 

Their engagement ruse 

…wasn't supposed to include desire! 

Lady Cecily Carlow knows she will never marry. No matter -- the money she will earn from her first novel should allow her to live independently. But when her odious aunt finds Cecily a rude but willing fiancé, she needs a plan -- fast! 

Felix, Duke of Garth, has a way to help his best friend: a fake engagement for the festive season! Felix will never love again after losing his wife, but making Cecily his temporary fiancée will see off her suitor. Yet, as Christmas draws near, the unexpected attraction between them grows shockingly hard to resist!
