My wife first recommended Lisa Scottoline books to me. She asked me to request this book from NetGalley and she read it first. She and I both give it 4 out of 5 stars. I have read 8 Scottoline books and my wife twice as many or more. She is reading a Scottoline book even as I write this. It starts with a bad guy identified right off the bat, but my wife said there's more to it. There more than a few twists and turns, but there is a very satisfactory ending.
I can't say too much more without going into spoiler territory. Some elements in this book: sexting by teenagers, a truck bomb and a dedicated ATF(Alcohol, Tobacco and Firearms) agent. There are a couple of typos--Glynco is misspelled as Glencoe. I spent some time training there and it is spelled Glynco. At one point a character is described as going from death to diagnosis in two months.
I recommend it to Scottoline fans. Thanks to NetGalley and the publisher for sending me this book.
