Twin brothers. One modified, one not.
The girl they both love.
A gene code their fathers want to force into the world.

Sage is kidnapped from her Kansas farm and held for ransom on a remote Pacific island. If she wants to survive, she must sort out the truth from the lies of her past.

Jack and Beckett have lived with their dad’s obsession of the mod code ever since the day they were born—and now he’s taking captives in attempt to get the mod code back.

Beckett will do anything to save the girl.
Jack will stop at nothing to destroy the code.
But doing either may require that the brothers let go of the one person they’ve both come to love.

From author Heidi Tankersley comes a thrilling new teen and young adult science fiction romance series, a thriller packed with action adventure and an unforgettable love triangle.

Praise for The Mod Code:

"Full of action, intrigue, and adventure, this story is one that stays with you and makes you yearn for more!" - Carrie Jones, New York Times bestselling author of the Need series.

"Fast paced thriller. Twists and turns. Nearly impossible to set down. I'm definitely looking forward to more from this fresh, new author." - A. Baker

“I just finished THE MOD CODE. I couldn't hardly put it down. I had to stop reading, so I could actually get some sleep. Is there a sequel coming? I didn't want this sci fi young adult series to end." -L. Burkert

"Fabulously woven plot with dynamic characters, led by a spirited heroine. This sci-fi romance book was thrilling from beginning to end—by far my new favorite." -Reader Review

"Such a thrilling story...I couldn't put it down! A must read for sure!" - L. Kelly

"I'm ready to read her next book. This was a great read. The characters were all interesting, and I'm still not sure who I want her to end up with! I highly recommend to anyone who enjoys young adult science fiction, some drama, action, and romance!" -Reader Review

"I loved this book and devoured it in two sittings. It would have been one sitting, but I had to sleep so the little one would have proper parental care! The writing immediately caught my attention and grabbed my interest. This book is quick-paced and well-written. I felt no "lulls," and genuinely care for the characters. I cannot wait for the next book in this young adult series so I can see how the Sage/Hope story continues. The concept is fresh and exciting; a fun read. I'm going to start the book over today, I loved it that much." -K. Estes

“Perfect for readers who enjoyed Twilight, by Stephenie Meyer or Divergent, by Veronica Roth!”

Customer Reviews

The Mod Code

It was a great book. I couldn't put it down and found myself wanting to read the next book. It was a great combination of the Hunger Games and Maximum Ride. Two books I find hard to top! This is a great read for teens and adults as well. Very detailed without all the pervasiveness some of the young reader books should not have in them. It's an all around good book for all middle school children to adults.
