Bianca D'Arc Resonance Mates

Resonance Mates series by Bianca D‘arc, (books 1-4)
1. Hara's Legacy: The first in a series of stories set in a future Earth, where the survivors of humanity must teach the Earth's new inhabitants what it means to be human... and to love.
The O'Hara brothers will do anything to protect the empathic woman they grew up with. But in a post-apocalyptic world, can they adapt to share her love if it's the only way to keep them all safe? It’s a serious game of cowboys and aliens when three psychically gifted brothers try to protect the one fragile, empathic woman who holds all their hearts against a menacing alien threat.
Montana rancher Caleb O’Hara’s precognitive abilities saved his family from an alien attack that annihilated almost everyone on Earth. Now the aliens have come to study the remnants of humanity. Caleb knows the only way to ensure the safety of his young wife, Janie, and his beloved brothers, Justin and Mick, is to keep the family together on their isolated ranch.
All three O’Hara brothers love Jane. They grew up next door to the young, empathic beauty and she stole all their hearts at one time or another, though she married Caleb. Caleb foresees the shocking truth of what they have to do in order to survive, and Caleb’s visions never lie.
They’ll have to come to terms with a new world, and an evolving relationship, all while finding a way to protect two newborn babies who are innocent pawns in the aliens’ deadly game. Somehow, this one talented family holds the key for humanity’s survival on this new, conquered world called Earth.

1.5 The O’Hara’s Wedding: See how it all started with this peek into the lives of Jane, Caleb, Justin and Mick on Caleb and Jane's wedding day.

2. Davin's Quest: Which man will Callie choose, the alien or the warrior? Or can she have both?
For each Alvian, there is one perfect match—a Resonance Mate whose soul blends in perfect harmony. Unlike the rest of his race, Davin has emotions and suffers for it. Without a mate, he is doomed to go mad. Searching for answers and understanding, he seeks out Callie O’Hara, a human woman with strong empathic gifts. Could this fragile human be his Resonance Mate?
Rick St. John is a tough-as-nails survivor of the Alvian occupation of Earth. He doesn’t believe in much, but when he sees Callie for the first time, he starts to believe in love at first sight.
The Governing Council is gunning for Davin, the upstart who dares to defy them. And they’ll kill anyone who gets in their way. Davin and Rick must come to terms with their feelings for Callie in order to keep her safe, while she has to find a way to save them both... with her love.

3. Jaci's Experiment: Love... the grandest experiment of all.
As a young Alvian lab tech, Jaci knows her place in the orderly, emotionless society her race has established on the planet Earth. While preparing a batch of experimental skin patches, she is accidentally exposed to a gene-altering agent. In a matter of days, she’s assaulted with raw, primitive, forbidden emotions she has no clue how to handle. If her superiors find out, she’s a dead woman.
Her only hope is to seek help from the human test subjects held captive in pens below the city.
Before the aliens came, cousins Mike and Dave used their psychic abilities to their advantage in business dealings. Now they use them to stay alive, keeping a sharp telepathic eye out for ways to help themselves and others improve their lot... or escape. Their friendship with Jaci has always been more than simply captives and caretaker. Now that her DNA has changed, their shared resonance is the stuff of legend.
Inevitably, Jaci’s emotions expose her to deadly Alvian justice. Suddenly she’s in the race of her life, seeking the only safety she’s ever known... in the arms of her human Resonance Mates.

4. Grady’s Awakening: An alien warrior discovers what it is to love…and to share.

Alien super soldier Grady Prime's missions routinely lead him in unexpected directions, but his latest assignment-to kill a rogue warrior-is far beyond routine. This time he meets a woman who embroils him in an adventure of the highest order. Love.
Gina has lived among aliens so long, she's lost her fear of them. She is undeniably attracted to Grady, even though their respective duties force them apart. Then, on a mission to a far-flung outpost, an encounter with a man from her past leaves her torn between her flaming desire for Grady, and her still-simmering love for an old flame.
Jim and his group of human dissidents live in secret, away from alien patrols. He has responsibilities, and covert operations to manage. But when Gina re-enters his life, only one thing matters-being with her.
Brought together by chance, the three form an alliance that pushes the boundaries of desire and make unexpected connections that could save the human race from alien conquerors...
