My Immortal Highlander (McNachton Vampires)

As identical twins, Bothan and Calum MacNachton share a bond stronger than most brothers, one forged by a terrible secret. Rumors and dark tales have been whispered about their clan for centuries.

They've heard the terrible, whispered warnings, but nothing could prepare them for the handsome brothers whose fierce, unyielding desires are beyond any legend... What Bothan and Calum promise is a life unlike any Kenna and Sarra have ever known. Now, Kenna and Sarra must choose whether to betray their dark lords or stand and fight for a passion that will never die...
