Shelves: sci-fi, apocalyptic
First in the Genetically Modified apocalyptic science fiction duology and revolving around Marinah. The couple focus is on Marinah Church and King.

This eARC was sent to me by BookSirens for an honest review.

My Take
It's a theme of betrayal by the politicians. A betrayal that encompasses so many areas. And I certainly can't blame King and his people for hiding all these secrets! Snicker, I did enjoy how Roberts portrayed the Shadow Warriors in their straightforward "thinking".

There is so much dist
This book is a genre-blender. Paranormal, Post-apocalyptic, Dystopic, Romance, Action-Suspense and Sci-Fi all make an appearance. I'm a sucker for a good PA novel, but shifters, not so much. This was a little toned down and the slow burn helped curb any "fated mates" worries. In fact, the H/h are not at all enamored with one another at the beginning. Roberts crafts a complicated world. Twists are prevalent. Plus, I really began to like the characters. Marinah is a woman who finds herself, uncove ...more

This is Shadow, book one of the Genetically Modified series written by Holly S Roberts. This book will keep you on the edge of your seat and so worried for Marinah the entire time. Have you ever felt overwhelmed and surrounded by wolves in sheep’s clothing?? What about barely contained beasts that ripple just below the surface of the huge men that are watching your every move? Trust me, you WILL NOT want to set this one down until the exciting cliffhanger ending! I’m gonna go sit in a corner and ...more

WOW!!! HIGHLY recommend this book!! 🌟🌟🌟🌟🌟

I've been a fan of Holly S. Roberts books for quite some time and THIS book SHADOW is just another example and why I LOVE reading this authors books, regardless of the genre. Holly has a very special gift as an extremely talented author, with a brilliant and creative mind. Holly has the capability to bring out different emotions by the reader, which I find extraordinary. I found myself laughing so hard at specific points in the book, which is wonderful be

So good

This book was awesome. It played like a movie in my mind as I read it. Seeing the heroine come into her own and finding strength was so cool. I did want to cry when it ended so I will eagerly wait for the next installment.

Shadow is an exciting new addition to the world of shifters, a world with Hell Hounds and Wolves. Shadow Warriors are fighters - fierce and big. They helped humans fight the hell hounds when the world was destroyed by war. Shadow warriors are half man and half beast. Marinah works for the Federation, what they call the Government now, and she is sent to meet with King, the leader of the Shadow Warriors to see if they could work together to fight the Hell Hounds. She was to go alone to meet with ...more

Fierce warrior

A brave young woman. A fierce warrior. Together they can save the world. An epic romance set in a fierce background of betrayal and war. She does not know what she is capable of. One man will show her. Their love story will capture you so deep. One of the best storytellers out there. Holly S Roberts has weaved her magic into a wicked story of love that conquers all. Thank you for this fantastic story

Following in her father's footsteps, Marinah Church is appointed Secretary Of Defense by the new President though she is only twenty four and has little to no practical experience other than analytical stats and figure tracking experience.

Less than twenty four hours after her appointment, Marinah is sent to negotiate with the Shadow Warriors on behalf of the United States Federation. It is hoped that they will agree to combine forces to deal with the invasion of hellhounds, virtual indestructib

Shelves: good
Cuba setting in apocalyptic world was great. The h is very tall and humble, arrives expecting to be killed by the H. But she pulled up her big girl panties, and prepared to do the right thing for her country before she dies. She's interesting, and the H was as intrigued as I was as she submitted to everything he threw at her. This book is the intro to a series about a depressing world. Too harsh for me, but the writing was great.
Pam James
In true Holly Roberts style, She makes you FEEL so many emotions. This book also got me so emotionally involved, I could not put it down. I fell asleep reading it, then finished it this morning. If you want to be taken to a new place, a new world, pick up this book and start reading. It is so well written and full of interesting new characters and new paranormal creatures you also will be emotionally involved! Loved It! From a True Fan... Pam James.

**This book was provided to Nerd Girl Official in exchange for an honest review.**

Shadow: Duet; A Genetically Modified Novel, Book 1 by Holly S. Roberts is the beginning of a post-apocalyptic story. It has people, and monsters, and monsters that help people fight the other monsters. Confused? Don’t be.

I warn you, this is going to be a very short review. Short even for me, and I can be known for short reviews. I’m making it short for a couple of reasons; first, I have to get to the next book!

This is Book 1 in A Genetically Modified Novel series. The world has changed and there are now humans, Shadow Warriors and the bad Hellhounds. King is the Leader of the Shadow Warriors and Marinah has been asked by the Federation to go to Cuba, which is where the Shadow Warrior’s live now. They want them to come back and save the humans. Or do they? This is not your regular paranormal type of book. King has his idea of what Marinah is there for and Marinah has her idea of why she’s there. But do ...more

I absolutely loved this book and couldn't put it down. Who doesn't love a hot headed sexy man who is also a ferocious beast who is protective of what's his.
Mirinah is a witty clumsy funny young woman who falls for the big bad King. The story was good and brought plenty of action and many laughs. Really enjoyed it and I can't wait to read Warrior.

This was a great, fun, thought-provoking read!!! Mostly light, with a few themes to make you think about our world in a different way. A friend's daughter was the inspiration for the female lead, and I bought the first two books to support my friend. Now I'm hooked and will be reading much more by this author, I hope!

Interesting premise, clunky writing that caused me to skim a majority of the book. Such a shame because the world building was almost interesting.
First of all, let me start by saying that the abstract describing the book is more informative than the book itself. There is no explanation for the current state of the world other than something to do with electromagnetic pulses and monsters. So, the world-building is severely lacking. The story line actually mostly focuses on (and traverses between as narrators) main characters Marinah and King and their relationship to one another. The allure of an apocalyptic/post-apocalyptic story takes a ...more

I don't generally like to give the 1st book in a new series a 5 star rating--oh, I will, but I don't like to--it sets the bar kinda high and that can lead to disappointment, distrust, and dismay. That said, I finished a beautiful spring day hike early just so I could get back and see what happened next.

Marinah (rhymes with Dinah) is not a very likely heroine. She's clumsy, lacks confidence, and is convinced she won't survive the plane trip the book begins with. (Spoiler alert--she survives the

I was enamoured from the first word. Marinah's dry, self-depreciating humour is engaging and I couldn't help but fall in love with her although her rather fatalistic outlook, whilst understandable, is a little sad, all you want is for her to grow a backbone and fight. Luckily as the book progresses this starts to happen. I couldn't help but adore King and his Shadow Warriors. Their beasts were never far from the surface but you can understand why they hate humans so much. The humans took their h ...more

Shadow: Duet

This Shadow Warrior story is amazing and so unique. I do not normally like post apocalyptic type stories but this one hooked from the start. The descriptions of the locations, people are realistic and it just add to an amazing plot. There are plenty of hints as to what is going to happen, but you read in to see how is going to come about.

I absolutely love the secondary characters and the way the flesh out the story. Che is one of my fave’s. Marinah and King have a complex relationsh

First let me state that I received an Advance Reader Copy, (ARC), but this in no way influences my review. I always leave an honest review. Also this author is new to me, and I hope it won't be my last.

Holy shiznet!! When I first started reading this story and hearing about the "hellhounds", I thought this was about the apocalypse. As I read so many things changed my mind, (obviously as the story unfolded too). I was a little upset with the fact that it's a sort of cliffhanger. But after Ms. Rob

"Nooooooo!!!!!! You can’t leave me there…" she wails into the night. This book has my favorite kind of geeky, socially awkward heroine. Marinah’s neither trained for, nor remotely prepared for the situation she’s suddenly thrust into. And King has no idea what to make of the creature that’s literally stumbled into his world. Imagine Resident Evil meets Wolverine. The story is a political thriller wrapped around what might turn into a romance, set in a post-apocalyptic world filled with supernatu ...more

I'm a huge fan of dystopian novels and novels and "Shadow" from Holly s. Roberts is one of the best I've read so far. It's slowburn in the romance department which makes it that much better. The characters have time to develop and are written in a way that you can emphasize (even though we are not overrun by hellhumans - errr hellhounds). The setting is described so that you can see it in front of your eyes. Thank you, Mz. Robert's, for a great read.

I would definitely recommend this book to thos

Awsome book, although I was bummed about the ending but I understand. I must say, I didn’t think I was going to like it. I continued to read to try to be fair. I was enjoyable surprised. This book is about a young woman named Marinah, who sets out to get the Shadow Warriors to help fight what she thought were hellhounds. She meets King who is the leader and decided that she was there to spy. Together the learn the meaning of survival and love.

They left her in a steaming room where she almost died in the first hour of meeting those shadow warriors that customarily do not harm women and children yet had no problem to just shove her inside without any worry. Even when one the guys wanted to save her another one was against it. I call this all bullshit, it's straight-up abuse and pure stupidity. I ended my patience at 25%.
I liked the premise but given that it's m/f, the shadow guy King is a dick, there is nothing that should pull me in.

This is a great start to a new series with skill-fully written characters . Will King the shadow warrior trust Marinah sent by the humans to apologise for the past. All is not as she has been told the enemy they are both fighting the hellhounds are not exactly hounds. I await the next exciting book in this series.
I was given an ARC of this book by the publisher in exchange for an honest review.

Wow, Just Wow.
I can't tell you how much I loved this book. It sucked me in from the very beginning. This is the first book that I have read from this author and I can't wait to see what happens in the 2nd part Warrior.
There's still a lot of the plot to see in Warrior, and Shadow has laid out some great world building, characters plots and sub plots. It's a real page turner. I received an advance review copy for free, and I am leaving this review voluntarily.
