The Duke Who Saved Christmas by Emma Hart

Sylvie Harding once swore that the only reason she’d ever return to Castleton was to plan her sister’s wedding… And here she is.
After eleven months of planning, the Christmas Eve wedding of her little sister’s dreams is only three weeks away, and professional wedding planner Sylvie is all hands-on deck from the moment she arrives home. Swept up in the magic that is Christmas in her hometown, the only thing that can possibly dampen her spirit is coming face to face with her childhood frenemy.
Thomas, the Duke of Castleton.
The man she spent her childhood feuding with thanks to an errant cricket ball is just as snarky, annoying, and gorgeous as she remembers. Despite running the village tree farm and his mother being the ringleader of all things Christmas in town, the past few years have turned him into a right little scrooge.
When a string of tragedies hit the wedding plans, Sylvie only has one person she can turn to: Thomas. Not that she has a choice—he has a habit of showing up exactly when she needs him to save the day, and she can’t stand it.
And when the ultimate disaster befalls the wedding just three days before the ceremony, Sylvie doesn’t see how it can go ahead.
But Thomas can.
And it just might be his chance to prove to Sylvie how he truly feels about her—and save Christmas at the same time.
