A Time to Wed by Ellie St. Clair

On the run from the life that has let her down time and again, Jaime Abernathy escapes to Scotland – where she falls through time and into the arms of a man from centuries past.

For years, Jaime has yearned to find a place she can call home – and has been let down time and again. She finally followed her heart to Scotland, the home of her ancestors. When she falls in the woods near her ancestral family home, she awakens with a pair of strong arms wrapped around her – and is convinced that she has finally gone mad.
Son of the laird of the McDermonts, Alec is torn between avoiding his arranged marriage and keeping peace with a warring clan. Convinced treachery is on the horizon, he needs a plan – and when he finds Jaime alone in the woods, he senses a way out.
When Jaime agrees to a fake marriage, little does she know the depths of Highland clan politics she is falling into. Finding herself caught between Alec and his family, she must help keep the peace before she returns where she belongs… if only she can discover just where that is.

This is a steamy Scottish time travel romance and was previously published as Bride for a Time by Audrey Adair.
