Arne by Hazel Hunter

She’s found the man of her dreams, but he’s obviously not real. Or is he?

When photographer Danielle Reeve is hired to document the restoration of a remote estate, she’s mystified but pleased. Though she’ll need to bring every bit of equipment she owns, it’s a break from the unending family portraits. But the photos of the mansion interiors, particularly the ballroom with its mirrors, reveal the ghostly image of a handsome warrior who seems to be watching her. Though only an illusion of the light, she is mesmerized.
Blade Lord Arne of the House of Eagles is a warrior of two worlds. With enough vassals and duties to keep ten men busy, he has let himself become captivated with Danielle. From the moment she entered his domain he can hardly take his eyes from her. But Arne also senses the hand of an ancient enemy at work, one who plays a very dangerous game.
Only when desire sweeps away all barriers does Arne understand what is truly at stake. He will have to break the most ancient of vows in order to make Danielle his.
