This was a free ebook that I downloaded. I really enjoyed this suspenseful tale. The story was full of action right up to the ending.

With some serious editing, this book would make a good movie. The plot is consistent with some of the action/adventure thrillers gracing the screen, and the concept is original, and one I haven't quite seen before.

That being said, this book needs a lot of work. The author uses a lot of descriptive language, and some of it is quite nice. However, those phrases are thrown into a mix of run-on sentences filled with grammar errors, and noticeably lacking proper punctuation (I'm not sure there is a c

When planes start dropping out of the sky and when people and their electronic equipment - computers and cellular phones - are baked and fried from a deadly energy pulse, the CIA, FBI, Homeland Security, and the President of the United States discover they are helpless against their own technology, which has been commandeered by a group of terrorists and turned against them. Without any plausible way for the government to prevent the terrorists from destroying the lives of millions of people on ...more

Dark End of the Spectrum is now the number 4 bestseller on Kindle. Take a look - the ending will floor you!


My newest book, Dark End of the Spectrum has received several reviews and they have caused me to nearly fall off my chair when I heard them.

When I finished writing the mystery/thriller, I thought it would appeal mainly to computer geeks, readers interested in technology, and people who knew their way around the Internet.

Not only does it appeal to these audiences, it also appeals to w

At 468 pages, Dark End of the Spectrum, by Anthony S. Policastro, felt rather long to me, but the pages turned quickly, even on a computer, and by the time the CIA arrived to take Dan away from his family on a sunny day off I was thoroughly hooked. I’m not sure what I’d have done then if my cell-phone had rung.

Dan understands technology. He talks about Ultra Wide Band transmissions and 512 bit encryption, and I wonder how out of date I am. But he’s plausible and convincing when he describes the

Enthralling book with an interesting plot that makes you read and read till the end.
The plot involves the latest communications technology and some futuristic inventions mixed with the worries and the day by day of a family man that becomes involved in a nightmare where thousands of people die and terrorists threaten the whole country.
He's a key man to defeat them.
