A Shadow in the Past - Melanie Robertson-King

Nineteen-year-old Sarah Shand finds herself thrust back into the past. There she struggles to keep her real identity from a society that finds her comments and ideas strange and her speech and actions forward, unlike Victorian women. When Sarah verbally confronts confining social practices, including arranged marriages, powerful enemies commit her to a lunatic asylum. After falling in love with the handsome Laird of Weetshill, Robert Robertson, she must decide whether to find her way back to her own time or to remain in the past with him.
