Tipping Point: The Fifth Tunnel

Rate this book
Artillery duels between the allied forces in South Korea and the seven thousand guns of North Korea ranged across the DMZ. With much of the North Korean aircraft destroyed during the preemptive attacks, South Korean and American attack fighters sortied from bases to strike at the leading North Korean columns. Skirmishes broke out between forward screening units. Nerves were on edge as the major ground units of the north and south were about to collide head-on. Will the southern defenses hold? Or will the masses of the north force their way through?

An anxious world looks on at North Korea’s use of chemical weapons. How will the United States respond? Will the use of weapons of mass destruction lead to a series of escalation events?

This episode got way too much into repetitive detailing of how the armaments, etc worked. Yes, each episode does that, but this crossed the line where I would forward my audio book 30 seconds until I was out of the bulk of it. Otherwise, I thought it was odd to have a complete book devoted the the crossing over to get near Taiwan and not land yet! Ha!

North Korea and China are battling South Korea and the Americans but what N. Korea doesn't realize is they are just pawns in China's plan for total world dominance. Another action packed tale from O'Brien. I recommend this book and series to any fan of the military genre.

Deceiving title

Had to write it again grr

So the fifth tunnel is at 99 percent of the book..

Battles are too one sided starting at two thirds of the book.

Seems like the writer was tired of the story already, and please don't put the maps after the action

Not sure to read the next one

I liked the tunnel description, so one percent of the book

Couldn’t put it down the entire series

Just finished the 6th book in the series. Couldn’t put it down, and couldn’t put any of the other 5 books down. There was some repetition in this book, but it didn’t distract me. Great word visuals. Learned a lot about the North and South Koreas geography and a lot about strategy. Battle scenes brought you right into the pages of the book.

The ending left me hanging as they left the 5th tunnel. I hope there is a 7th Korea and an 8th and 9th China.
