The Triad Trilogy - The Triad Series

Visit far off planets with telepathic humans, aliens and the occasional four thousand year old frozen Viking.  The Power of Three Soreya Lang has never met a male telepath before, let alone one who is willing to die for her on an interplanetary mission gone wrong. Risking everything, she acts on her instant telepathic and physical connection with Esca and encounters a level of psychic power she never knew existed. Esca can't believe he's finally met the female who will complete his sexual and telepathic triad.
He promises himself that if they survive, he'll take her back home, introduce her to his enigmatic First Male, Ash and pray that biology will do the rest. But nothing is ever that simple, and Soreya, Esca and Ash will have to find their own way through the ties of family and traditions to experience the full telepathic wonder of the power of three. The Power of Persuasion Ex super-soldier and telepath Captain Ian McNeill isn't expecting his job as base commander to a bunch of scientists to be exciting, let alone terrifying.
But after meeting Neeve, a Pavlovan female and saving her from a bunch of Etruscan extremists, he's fairly certain his life will never be the same again. Neeve can't believe she's found a mate from Earth who has no understanding of the concept of a bonded telepathic triad. Can she convince him to return to Pavlovan, meet her exalted but complicated family and finally convince him that adding a third to their bond will be the best decision he's ever made? Viking Unbound Encased in ice, traveling through space and thousands of years adrift from his world, Viking Einarr Bloodaxe can't help but respond to the call of his female and finally break free of his magical entrapment. For this woman he's willing to defy everything-even time.
