"UNFORGETTABLE," by Eric James Stone, Baen, e-book $8.99, 248 pages (f)

Nat Morgan is entirely forgettable — no person or computer can remember him after he’s been away for 60 seconds. It’s helpful in his career choice as a CIA agent, even if he has to remind his handler who he is every time he calls, in local author Eric James Stone’s debut novel, “Unforgettable,” scheduled to be released Jan. 5.

Nat’s talent of being forgettable allows him to be somewhat of a ghost and to procure items and information for the CIA. While on a mission in Barcelona to steal a prototype of a chip designed to break some of the most secure encryptions, he’s not the only one trying to steal it. Yalena Semyonova is after it for the Russian mob.

After the heist goes badly, including both of them being handcuffed together, Yalena remembers him, which is a novelty for Nat.

Their missions intersect as Nat is trying to stop a billionaire from finishing a quantum supercomputer and Yalena wants to find her twin sisters, who she suspects were sold as sex slaves.

“Unforgettable” is set in the near future, and it’s a dizzying and unrelenting adventure as Nat and Yalena go from country to country and use each other’s talents and skills to help an Iranian physicist who wants to defect, prevent the missing piece of technology from falling into the wrong hands and find Yalena’s sisters.

Nat falls in love with Yalena but realizes having a relationship with her is unrealistic, not to mention some other hurdles.

The quantum physics discussions may take those without a science background a couple of times to get a grasp of what they are saying. Fortunately, Stone realized this as it takes a few times for Nat to understand some of the science.

There are a few times when the second-by-second descriptions of some of the beginnings of Nat’s missions can bog down the storyline.

Overall, “Unforgettable” is a memorable novel in which Stone packs many adventures and new technology that is both exciting and frightening if it gets into the wrong hands. While the book is a stand-alone novel, its ending is open for a sequel.

There is no swearing or described sexual content beyond kissing. The violence, including heists, kidnappings, shootings and knife fights, is generally described.

Stone, an Orem resident and graduate of Brigham Young University and Baylor Law School, won the Nebula Award for Best Novelette from the Science Fiction and Fantasy Writers of America in 2011 and was nominated for a Hugo Award in 2011 for Best Novelette.
