Highlander Warrior by Rebecca Preston

Flung back in time by a terrible car accident, Cora must find her destiny in the wild Scottish Highlands — and escape the murderous plot that ended the life of her ancestor before it’s too late.

Cora Wilcox has been trapped in a maelstrom of depression since the disappearance of her dear friend Audrina. As a midwife, Cora has seen her fair share of joy and heartbreak, and after a particularly tragic evening, Cora is injured in a horrific car accident. Instead of waking in the hospital, she instead finds herself in a green field in the medieval Scottish highlands.
The Lady of the castle is in her childbed, but something isn’t right, and the midwife is nowhere to be found. Riding hard to find help for his Laird, Ian MacClaran is literally thrown into the lap of a young woman in strange clothing who happens to be exactly the help he is looking for.

Coming to terms with spending the rest of her life in this new reality was one thing, but it’s the way Ian MacClaran’s hazel eyes won’t leave her that is sparking something inside her that she never thought possible. However, Cora’s identity in this world has the potential to bring ruin upon the Clan, especially if a familiar enemy discovers that she has returned.
