Once Upon a Summer Night: Mists of Fate - Book Three

As one of the O'Rourke time-traveling Protectors, Colin O'Rourke is destined for one woman only. His instinct tells him he's found her when she wanders into his cousin's garden, but she's as enigmatic as she is charming. He vows to find her, but first, he has to deal with his professional life. He's about to take his matchmaking business overseas, but a prominent gossip columnist publishes a slanderous article about is company, threatening their success before they even open their doors. The columnist agrees to retract her article...if he can successfully match her stubbornly-single niece. 
Eleanor Carberry is content with her life as a London bookshop owner. She has everything she needs―books, tea, and an aunt who is more like a mother. With all her aunt has done for her, when she asks Ellie to try out an American matchmaking company, Ellie reluctantly agrees.

When Colin and Ellie meet, they immediately recognize each other―Ellie as his soul mate, and Colin as the man from the garden. Colin's bound by contract to find Ellie an Englishman...and if he doesn't, he'll lose the business he's worked so hard to grow. Despite the distance he tries to keep between them, Fate has other plans when Ellie takes an unexpected trip back in time...once upon a summer night.
