Memory of a Highlander by Katy Baker

She fell through time; he stole her heart.

Charlotte ‘Charlie’ Douglas likes her world ordered and predictable. So when she steps into a bookshop on a rainy Edinburgh afternoon, the last thing she expects is a cryptic warning from a strange old woman or to be swept from the bustling streets of the modern world into the wild and untamed 17th-century Scottish Highlands.
Niall Campbell is a man of two worlds. A Highland laird and a government agent, he will do whatever it takes to protect his people. So when a mysterious woman suddenly bursts into his life, he’s immediately suspicious. Her strange speech and otherworldly ways make her a puzzle he’s determined to unravel. But as their fates inextricably entwine, Niall begins to realize that she may hold not only the key to his clan’s survival—but to his heart as well.
As they navigate perilous clan rivalries and their growing attraction, Charlie faces the haunting question of why she’s here at all. With her heart torn between the life she left behind and the passion she’s found in the past, she must uncover the answer before time itself forces her hand.
