AT Once by John W. Mefford
I received a free copy of this book in exchange for an honest review. I absolutely love this author and this series. Each book is entertaining, engrossing, well written and a page turner. The bombing in Boston hits close to home, as I live in Mass and had a semi front row seat for the Marathon Day bombings because I was watching the Red Sox game at the time, but this book is so engaging I couldn't put it down.
