reviews, the readers (including some in Joplin that experienced the tornado) who are not associated with the National Weather Service love the book while those associated with the NWS despise it. Why? Because it tells the story of how the storm warnings failed the citizens of that city allowing scores of unnecessary deaths to occur. I'll let you read it and make up your own mind.
The paper copies of Sirens sold out within a couple of months of it going on sale but the ebook version is available. We priced the ebook very inexpensively -- $2.99 -- because we want everyone to read it, including the detailed tornado safety rules at the end. Those safety rules are broken down for home, school and work. The book is 67 pages and is a quick read.
By the way, you do not need a Kindle or Nook or other device to read Sirens. Just go to: read.amazon.com
and it will give you the ability to read Sirens or any other ebook without a dedicated device. It is quick and easy.
