A must read for public executives
Format: Paperback
Concise, focused, and full of real-world point and counterpoints, I found this to be more of an essential piece of oratory combat equipment than a book. As a non-lawyer working in public service, this book provides excellent points on interpretation, form versus substance, and the importance of observation and evidence – all skills needed to protect the public interest. As someone who monitors contracts in the public sector, many of my peers could benefit from this book and better design contracts to the advantage of their public entity. Incidentally, I was also involved in a heated discussion about data interpretation the same week I was reading this book, and was able to calmly defend and dominate the discussion until my opponent acquiesced. More important than dominating your opponent is the theme throughout this book that one’s argument must be genuine, and the logic tight. Additionally, as Prof. Trachtman reminds readers that these skills, like a weapon, should only be used for good. A great read!

What our kids need to hear
Format: Hardcover
This book says exactly what our kids need to hear in these confusing times. There are so many things that our children hear and see these days that it can be overwhelming and confusing. This book and the sweet illustrations make teaching our kids how lucky we are to live in the US so very easy and important. This is something we need to make sure our children appreciate and they will grow up proud to protect our freedoms afforded to us by so many. Love this book!

Simply Wonderful
Format: Hardcover
I Love America is a wonderful book to help children (along with the rest of us!) recognize and appreciate the blessings bestowed upon us by God, including our freedoms in all their forms, our remarkable veterans, and those that work so hard to make our nation what it is. The fun rhyming and adorable illustrations kept our boys glued to it the whole time. Highly, highly recommended.
