Sleeper Agent: Nemesis

Sleeper Agent #3

by John Birmingham, Rupert Degas (Narrator)

Genetically engineered to be the perfect weapon, Cooper Fox must now use those abilities to stop a shadowy cabal from rewriting the future of humanity.

Cooper was created by a clandestine government program, imbued with superhuman speed, strength, and reflexes. But when the program was sold off to the highest bidder, he has found himself caught in a deadly game of cat and mouse with the Consortium, a cabal of billionaires determined control of the world through any means necessary.

When the Consortium captures his partner Kristin Hegel, Cooper infiltrates their heavily-fortified research facility to mount a daring rescue. What he uncovers is more horrifying than anything he could have imagined – a plot to chemically subdue the global population and elevate a new breed of genetically enhanced "Guardians" to rule over the compliant masses.

With time running out, Cooper must confront his own troubled past, navigate a web of betrayal, and stop the Consortium before they can reshape the world in their image. Packed with pulse-pounding action and mind-bending sci-fi, Sleeper Nemesis is the thrilling finale to one man's fight to save humanity from those who would seek to engineer its evolution.

Got this through Audible but did not realise that it is #3 in the series. Stands on its own most of the way, but just something I find personanly frustrating...

Apologies to JB but this feels like what I wanted Tony and Ziva to be: fast moving with excellent action and violence and lots of gadgets...

Loved that the narrator/reader really got into the story as well and this helped mainatin the pace.

Enjoyed the listen - long daily commute - as a time-passer, will probably try some of the others in the series, certainly earlier volumes to cathc up on the first parts of the story...

Very slow. Not as good as the first 2 books. Stuck it for 6 hours then gave up.

Some curve balls in this one. Last of the trilogy.
