Cliff Hanger! This book lost some steam in the middle. It dragged on a little too long to keep me completely interested, but once you wade through that portion of the book it gets going and I stayed up to read the last half of the book only to find out that there is obviously another in the series since this one provides no closure. Overall a good book, stick with it, it is worth it in the end although it leaves you with more questions than answers.
As always, Meltzer delivers an engaging plot with multiple layers. Throughout the book you will be guessing who the assassin is an like me, you will probably change your mind a few times. The Culper Ring figures prominently in this story and the tension between them and the President will definitely keep you wondering how it will all end. I recommend the book to any one who enjoys a good "whodunit" and has a conspiracy theorist mentality.
