The Academy stole everything from Hades, their perfect assassin. Angry and leaving bodies in his wake, he finds two other ex-assassins doing the exact same thing.

Tyler and Shannon once killed for The Academy. Now they’re tracking and hunting down its scientists. So why is The Academy only after Hades?

Shannon will do whatever it takes to protect Tyler, even if it means teaming up with a former rival. While she seeks answers to her past, Tyler wants to learn the truth about the mysterious white room, which no one has ever seen except him.

As for Hades? He simply wants revenge.

They all need answers, even if it means returning to the organization where it all started.

The Assassin Fall series is best enjoyed in order.

“If you're a fan of genetic engineering, conspiracy theories, and anti-heroes, you can't go wrong with this thrill-ride of a series.”  — Teri Polen, author of Sarah

“Hades was my favorite of the trio. His character was the one that was written in depth in this one...Action packed...” —Tammy, Goodreads Reviewer

“Really outstanding!! It's scary because it's possible, unfortunately! The characters have been drawn so well that the reader knows them! It is a hard book to read and also a hard one to put down!!” —Jeannie Huie, Goodreads Reviewer

“What drew this book to me initially were the mythological associations and, hello, YA sci-fi. What kept me in drawn in were my favorite things a book should have: attention to dialogue, description, complex main characters, and showing rather than telling. This is a hard one to do, and very few authors do it well. I very much enjoyed the alternating perspectives to give a fresh take.” –Sarah, NetGalley

“The series is definitely fast paced and action packed which I love!” –Carrie’s Book Reviews

“Another lovely piece from Aden Polydoros. The plot is active and fast-paced, and my heart stayed with Hades the entire time. Polydoros does an incredible job of balancing back story with the action, and I loved the entire series!” –Deborah M., NetGalley

Project Prometheus by Aden Polydoros is the second full length novel of the young adult action packed Assassin Fall thriller series. There is also a prequel novella to kick off the series and it is best to read the books in order or in the very least the two full length books in order as the second ...more

A special thank you goes out to Entangled Teen for allowing me to read this eARC early. All thoughts and opinions are my own. A super special thank you goes out to Aden Polydoros for sending me physical copies! You are the best!!

4.5 stars!

I am not okay! Nope. Not one bit! Aden Polydoros has complete ...more

This second book was pretty close to as good as the first book. In book one you really felt the connection between Hades and Elizabeth, and you got to seeing him as a character that you had sympathy for and could definitely begin to like. By the end of this story, after all that happened, I felt eve ...more

By Tammy July 27, 2018

Hades was my favorite of the trio. His character was the one that was written in depth in this one. Tyler and Shannon were likable too but their stories didn't draw me in the same way. The beginning took me a while to get my head into the book but once I did the book was quickly devoured. Action pac ...more

I absolutely LOVED the first book in this series, Project Pandora, which amazingly enough was Aden’s debut (a fact that still shocks me considering how well it was written and how much it affected me). I talked in my review for that book how much I ached for Hades, how I wanted to just hold him and ...more

While the first book was already action packed, this second one in the series succeeds in heightening the tension a notch more.

After their escape, the kids from the project, where they were trained to be assassins and committed terrible crimes without their knowledge, decide to fight back. Told fro ...more

The first book in this series, Project Pandora, was one of my most addictive, electrifying reads last year, and I didn't think I'd survive the wait for book two.  I made it (barely), and dove right into Project Prometheus - and it's worth the wait.

Since he's mentioned in the blurb, I'm not giving an ...more

Interesting character development!
Thanks to NetGalley and Entangled Teen for the opportunity to read and review Project Prometheus by Aden Polydoros!
This sequel dives deeper into the effects of Project Pandora. My heart broke for Hades. His story is made more powerful through the alternating points ...more

I received this free from NetGalley and the publisher for an honest review.
This is the second book in the Assassin Fall series by Aden Polydoros. It is imperative to read these books in order or you will be lost. Teens are being brainwashed to do whatever a cabal of adults wants them to do, usually ...more

A third book as beloved as the others.

We learn that the academy stole everything from Hades, the perfect assassin and bodies are left wherever it goes. He finds other assassins who leave bodies everywhere ...more

Project Prometheus is a twisty second book in the Assassin Falls series. It has several political views points, but not overpowering for those who don’t like reading about politics. The addition of Project Prometheus and it’s role in the story is a twist and something I thought was a unique aspect t ...more

Nicely crafted dystopian tale. The three main characters are easy to relate to and the reader can understand what drives each of them to do and think as they do. Not having read the first book, I ordered it as soon as I finished with this, so I can get the full story and I'm interested to see where ...more

Really outstanding!! A great read, but be sure to read book 1 first or it won't make sense!! It's scary because it's possible, unfortunately! The characters have been drawn so well that the reader knows them! It is a hard book to read and also a hard one to put down!! ...more

Excited didn’t even begin to come close to what I was feeling when I saw that book 2 in the Assassin Fall series was up for review.
