Partners Emmett and Theo are kidnapped by a shadowy organization bent on learning their secrets. Taken to a private lab, they meet Dr. Riley Walker, the brilliant, beautiful geneticist charged with discovering what they are.

While Riley believes they’re aliens, Theo and Emmett realize she’s their mate. But she’s also the enemy—

Or so it seems.

Theo and Emmett aren’t the only ones with something to hide.

The three are caught up in things they can’t control. Nefarious forces are at play. Unseen eyes are watching them. After Riley is forced to betray them, the feelings the partners have for the new female in their life take a twisted turn.

When truths are exposed, the whole cadre’s mission is put at risk. Emmett and Theo must fight for the woman who’s destined to be theirs or lose her to a dark, dark fate.

Shifters with a sci-fi twist, Guarded Hearts Season One (Books 1-7) follows members of The Order of the Phoenix. Each book in this interconnected storyline provides a happily-ever-after for the main characters. While the first book of Season One can be read as a stand-alone, the following titles will be more fully enjoyed and understood if they are read in order, beginning with Morgan (Guarded Hearts Book 1). MMF ménage erotic romance with MM scenes, written for Ages 18+.


EXCERPT from Riley:


Riley knew better than to argue.  Skinner was the puppet master, pulling all of their strings.  Retreating to the cafeteria, she took a seat and waited, watching the clock and observing others who came in for coffee or something to eat.  Skinner’s pet, Dr. Lewis, gave a nod of acknowledgment and disappeared through the kitchen door.  When he didn’t come out, she assumed that Skinner had sent him to make certain his orders were followed to the letter.


A short time later, the chef with a laden cart and Dr. Lewis appeared.  Mouths shaped with knowing smirks, the two men eyed her like a piece of breakfast meat.


Christ.  Did everyone know what Skinner wanted?  He was no better than a pimp, expecting her to use her sexuality to get the results he wanted, samples of body fluids he could test for DNA.


“Here’s everything you requested,” the chef announced, pushing the stainless steel cart into place beside her.


The top held three trays with covered dishes and three steaming mugs of hot beverages.


Riley arched an eyebrow.  “What’s this?”


“Black coffee, Earl Grey, and a mocha latte for you,” Dr. Lewis answered smoothly, pointing to each in turn.  “I advised Skinner that sharing a meal with the specimens would make them more at ease around you.”


It made sense.  Eating together might allow her to form a bond with the subjects—or at least help Emmett to lower his guard and let her explore things with Theo.  It was a unique opportunity, giving her an excuse to spend time with them and providing the means to study them up close.


Dr. Lewis followed her, whistling softly, making her feel increasingly leery about this whole thing.  Skinner had sent him to observe her interactions with their subjects.  The cameras were impersonal, something she was aware of but had learned to ignore.  Having a witness seemed… lurid.  Voyeuristic rather than scientific, despite what her rational mind said.  Skinner expected results.  It was in her best interest to see that he got them.  If she failed, she feared that all three of them would suffer.


One of the guards reached to open the door.


“Dr. Walker.”


Hearing her name from Skinner’s minion, she fought the urge to not shudder with dread.  “Yes, Dr. Lewis?”


“Good luck,” he said smoothly.  “We’ll be watching your interactions closely.”


Riley’s stomach somersaulted unpleasantly at the thought.  Taking a deep steady breath, she wheeled the laden cart into the cell, suppressing a shudder when the door clanged shut behind her.


Emmett and Theo were waiting for her.


The Englishman cocked an eyebrow above his glasses when he saw the cart.  Moving to inspect the contents, he lifted the plate covers and nodded in approval.  “Well done, Miss Walker.”


Theo beamed, his teeth flashing white against his tanned skin.  “Thank you.”


“I thought we could share breakfast together,” she told them.  “Why don’t you have a seat, and I’ll serve you?”


They exchanged a look.  Again, that silent communication, one of them eager, the other taciturn.  Having no other options, they sat on the bottom bunk with Emmett at the head and Theo in the middle, leaving room for her at the foot of the bed.


They ate in silence.  Riley was aware of the sidelong looks Theo sent her way.


Emmett ignored her.


“I hope your tea’s alright.  I’m more of a coffee drinker myself,” she commented, enjoying her mocha.


“It’s acceptable,” the Englishman clipped, sounding annoyed at her attempt to engage him.


Theo cleaned his plate and drained his coffee cup.  Finishing her breakfast, Riley cleared her throat and shifted uncomfortably on her perch. There was a spreading warmth coursing through her veins, leaving her feeling flushed and filling her with an awareness of her body.


Emmett was the last to finish, his throat muscles working as he drank the rest of his tea.


Sitting beside her, Theo had satisfied one hunger but another one burgeoned… Pulling her to her feet, he hauled her against him, fisted her hair, and ravaged her mouth with the hottest kiss she’d ever experienced.

Let me start with a warning -

Yes, each of the past throuples has had to overcome some major hurdles but what lies in wait for Riley, Theo, and Emmett?

An eternity trapped in the darkest of nightmares would have been kinder

There were moments for me that I had to step back and take a moment, broke my heart 😢

And the betrayals?

They just kept coming! I would think they had a chance - then BAM!

I'm emotionally exhausted

Theo and Emmett screw up right from the start.

And Emmett just keeps digging that hole deeper!

You should know better Emmett! I was pretty mad at you for most of the journey.

Theo, you are just a sweetie 😙

Riley, I get you were not sure and a touch freaked out (who wouldn't be?) but I think you took your revenge a bit too far as well.

That being said 🤨

I know you will eventually find your rhythm as a throuple and forgive each other their transgressions

May have to visit the "ship" a few times 🤣☄ but that's half the fun

Let me not forget Etienne. I knew he was capable of evil, he has always shown no remorse for his actions. But what he did here?

I wish upon you a plaque - may you someday relieve the pain you have caused the innocent who fell under your wrath tenfold.

There was a certain revelation that was revealed in this episode that threw me for a loop. One of my favorite characters in the series has been hiding a pretty big secret. I know 'golden boy' didn't do anything wrong per se' and he has his reasons for not telling anyone (which after watching the reaction to Riley I get). We can't control who steals our heart. I do however have all kinds of questions for him.

Big changes are coming to the Citadel

Not all pleasant ones or ones that can be easily fixed but I think as our little family expands and the familial bonds grow stronger the enemy(s) may find it harder to take them down

This episode was chock full of "OMG" moments, "WTH were you thinking?" moments, and some seriously steamy "MINE" 💦scenes

as well as some scenes that could be triggers for the reader - both emotional and physical - including noncon

Be prepared for an emotionally charged ride!

This is not a standalone so ✋ back it up if you have not read the previous releases or things won't make a whole lot of sense
