Alpha Instinct (Moon Shifter Book 1) Kindle Edition

The first addictive novel in USA Today bestselling author Katie Reus’s Moon Shifter series.

He ghosted her years ago…

Ana Cordona has been a strong leader for the lupine shifters who survived after half her pack was murdered. As tough as she is, her pack is vulnerable to a devious neighbor who wants their land—and Ana as his own. So when a ghost from her past barrels back into her life promising protection, it’s almost enough to make Ana forget how he walked out on her before—and reluctantly accept his offer to mate.

Now he’s back.

Connor isn’t walking away again. Ana has always been his mate, something his wolf accepted long ago. And the only reason he left before was for her own protection. Whatever it takes, he’s determined not to leave her side again—but danger is all around them in the form of a rival pack and a radicalized human element in town who wants to destroy all shifters. If they want a chance at a future—and to survive the deadly threats closing in—they’re going to have to learn to trust each other. Unfortunately, the danger is closer than they ever imagined.

SECOND EDITION - This updated and revised edition is the author’s preferred text.

Author’s Note: Alpha Instinct was originally published by Berkley and the rights have recently reverted back to me. Since then, I’ve done some light editing and rewriting. So if the cover looks new but the title feels familiar, that’s why! I wanted to make sure that those who have read this, didn’t accidentally purchase this again. But for new readers, I hope you enjoy.

I liked Ana, she was doing the tough job of keeping family together after losing so many. Connor was flawed, but strong, trying to do the right thing. Good mystery, good action, good romance. I very much enjoyed this story.

Alpha Instinct by Katie Reus
Moon Shifter series #1. Paranormal wolf shifter romance.
Ana Cordona is the current leader of her pack after a devastating poisoning by an unknown enemy ended with all the males dead. Her pack is also under threat from the Sean Taggart, the devious alpha shifter that owns the closest ranch. She can turn down his offers but he’s not above blackmail or force to get what he wants. Surprisingly, Connor Armstrong returns to her lands with a group of warrior alphas. He is prepared to offer his protection. He’s always known that Ana is his mate, and he also knows he needs to move carefully to convince her to give him a second chance. He had a reason for leaving the first time but sharing it and getting her to trust him will take time. Additional outside threats to Ana and her family have the timetable changing to fast forward.

Dark and obvious manipulative moments had me really disliking Taggart. I wasn’t sure Connor was any better with his less than subtle demands but he eventually proves he has the packs best interest at heart and that he really does care for Ana and her family. Alpha men. Love em or get rolled over by them. Connor and his men do have their softer feelings and vulnerabilities and I was amused in their trying to go slowly in proving their worth.
Suspense and investigation, steamy drama, retribution and so much more. Not a cliffhanger but clearly more stories, more enemies, and more pairings of these alpha wolves to forge their lives and futures together.

Original publication 2012.

5.0 out of 5 stars A dangerously good read!
Reviewed in the United States on February 8, 2024
I really enjoyed reading Alpha Instinct. This book is not just about the second chance romance between Ana and Connor, it’s so much more!

In the Moonshifter series, the secret’s out that shifters and vampires exist. It’s been a grueling process for the otherworldly creatures and humans to find an equilibrium in which to live peacefully. Discrimination against shifters and vampires is rampant, and the hate groups are vicious in their persecution and extermination of them. What people don’t realize is all the shifters/vampires want is to live in peace, raise their families and live happy lives. A few bad apples give otherworldies a bad name. But not all shifters are bad, just like not all humans are good. Sound familiar?

Okay, back to the story: Ana’s pack is left vulnerable because a sickness has spread through her pack months before killing all the males, pregnant females, including Ana’s dad–the alpha–her mom, and other pack members, leaving Ana the default alpha. Poor girl has to pull herself back together to protect the ones that remain and figure out who poisoned her pack. A grueling task, but she’s the alpha’s daughter, her strength and fierce protectiveness is admiral, and much needed.

As the story begins, Ana finds herself in a deadly situation when she hears a voice she hasn’t heard in a long time: Connor Armstrong, her first love and the man who walked out on her without a word. Connor and his brother Liam are back in town with a pack of warrior wolf shifters. Connor has an offer for Ana: Mate me and you’ll have my pack and my protection. Pretty romantic, right? Chaos definitely ensues.

The story is engaging, entertaining, and deadly. Ana and Connor have good chemistry and I love how strong she is and how she stands up to Connor and his pig-headed, overprotective alphaness. I love that there’s a lot of characters with diverse personalities. I really enjoyed reading about the political climate of the story and the diverse judicial systems humans and shifters/vamps/otherworldies have.

I am a sucker for a paranormal romance and to throw in a second chance romance on top of it while sprinkling in some mystery and suspense? Yes, please!

I can’t wait to start the next book!

Highly recommend it!

4.0 out of 5 stars second chance with a family twist
Reviewed in the United States on November 30, 2023

Ana and Connor. A shifter romance, but with several suspense/intrigue angles. The look into pack law and such was interesting and this story created a great world and pack dynamic with book one. The addition of the pup and cub was adorable and Vivian was probably the sweetest part of the story. Vivid descriptions of the characters and their emotions. The bad guys were split form two different angles, but created some great confusion and mystery to the story. Connors backstory for leaving Ana was sad, so their path to openness with each other was full of pack history and current events. A quick and fun read that also introduced who I believe will be the love interest in the next book…a human!

Reviewed in the United States on February 11, 2024
Action, suspense, intrigue, murder, rivalry, and obsession among the wolf shifter packs! Their reality so rich, seems like they live in the next town. Wolves and humans living in tense harmony as biases weave disharmony and mistrust, sound familiar? Strong characters, intense storylines, with action and emotion as fated mates struggle to be together. Can't wait for more!

4.0 out of 5 stars Great start to the series!
Reviewed in the United States on March 19, 2024
Love this start to the Moon Shifter series - Ana is the Alpha of her clan which has been devastated by illness, leaving only female shifters; Connor returns after 10 years away, having established himself in the world, but yearning for a clan, and his mate, Ana.. Together, while learning to trust each other again, they reestablish their relationship while working to discover the causes of the deaths and continued illness in their pack and the culprits of attacks occurring. Alpha Instinct is steamy, emotional and action-packed, While this book can be read as a standalone, it also sets the stage for the underlying plot that runs through the series, involving their challenge in overcoming the organization that was formed to destroy them.

Ana and what is left of her decimated pack are managing but their shifter neighbour is power hungry and threatens to rape her. Then an old flame shows up and interferes with the threat. Connor still is besotted with Ana and things hear up.
