Peek Inside Quantum

Someone wants Captain Admiral Zander Graydon dead. Like yesterday. Zander’s convinced his attractive assistant knows more than she’s willing to say, and if he can stop running long enough, he’ll find out exactly what she’s hiding. Lieutenant Marshal Mae Petros is determined to keep her CO safe. Before she tips her hand, however, Mae has to figure out if the alluring man she’s protecting is the real Captain Admiral Graydon. Or an alien shape shifting imposter.

On the run and no one to trust…not even each other.

Someone wants Captain Admiral Zander Graydon dead. Like yesterday. Almost getting killed three times in one day is pushing it, even for Zander. He’s convinced the delectable Lieutenant Marshal Petros knows who’s behind the attempts on his life and he’ll do whatever it takes to discover what she’s hiding.

Shape-shifting aliens are assassinating political and military leaders and assuming their forms, and Mae Petros is suspicious as hell of Zander Graydon. Mae is on a mission to determine if the captain admiral is still human but finds herself losing her perspective as they run for their lives. There’s no way she could be falling for an alien. Right? Especially when all of humanity is on the line.


- Can I give it 6 stars?...This is the best damned futuristic/sci-firomance novel ever...The relationship and romance between the two sings with tension and steam! - Diana Davis, Goodreads

- Thus far, I've been thrown for a few loops, laughed at the dry but engaging banter, been taken on an action-packed ride through some twists and turns I never saw coming and pretty much went down the long slide to a place no reader wants to go because it reeks of desperation: stalking the author for updates and news on the next book. - PiperKelly, NetGalley

- Just finished reading Quantum by Jess Anastasi...I'm exhausted. OK, yes, it's 3 am and I couldn't stop when I was so close to the end...okay, so maybe I wasn't all that very close, but hey, end was in sight and I needed to get there...- KJ VanHouten, Goodreads

- While the romance is very much there (& pretty amazing), this series is so very much more than a romance. It has just about everything; a fantastic story line, plot, action, romance, humor & snark!, worldbuilding - you name it. - Linda, Goodreads

As with quite a few of Jess Anastasi’s books, I’ve learnt the hard way that the blurb is always insufficient in mapping out just how little it says of her expansive universe and the huge number of things that she’s got going on in it. Zander Graydon and Mae Petros might be the pairing that’s given p ...more

Sci-fi, romance and bugs (bugs!?!) made for a great mix!

This is the second in the Atrophy series and it took everything I loved from Atrophy and amped it up a whole bunch of notches! This author has a flair for mixing the best elements of science fiction, romance, suspense and humor into stories tha ...more

I've been stalking the author waiting for the next book in the Atrophy series to come. The first book was freaking awesome before I even finished it I was already looking for book two.

Sci-fi Romance yummmmmm. This is the sequel to last years Atrophy. Captain Rian Sherron and the crew of the Imojenna are back with a little help from their friends. It's not necessary to have read the first book but it wouldn't hurt just for the added background of the characters and thei ...more

It took me a little bit to get into this story because it had been so long since I had read the first one, Atrophy and I just didn’t feel there was enough recap to catch me back up.  I feel if you were reading these stories back to back you would be totally fine.  If you are like me and read hundred ...more

Ever since my first Jess Anastasi book, she has been a go-to author for me. The way she spins an epic tale of sci-fi action with heart grabbing romance is an all around win as far as I'm concerned. Put it all together in the form of an epic series, satisfying my urge to remain with the same base lin ...more

About the author

Jess Anastasi

Jess has been making up stories ever since she can remember. Though her messy handwriting made it hard for anyone else to read them, she wasn't deterred and now she gets to make up stories for a living. She loves loud music, a good book on a rainy day, and probably spends too much time watching too many TV shows. Jess lives in regional Victoria, Australia, with her very supportive husband, three daughters, one ball-obsessed border collie, and one cat who thinks he's one of the kids.
