Wow this was so great! When I started it, I was at first a bit disappointed because the set up took some time and it seemed a bit slow. But that certainly changed rather quickly. This is the 5th in the Orphan X series and it seems like it may be the last. I really hope not. It starts with the death of a forensic accountant and speeds up to multiple feats by our hero that rival superman or a jedi knight. The reader must really suspend disbelief, which I did most willingly. Orphan X, AKA Evan Smoak, AKA The Nowhere Man is a super hero who apparently can win against the bad guys even with a severe concussion and blown pupil in one eye. When he was a child in an orphanage, he slept on the floor before being "rescued" to be trained to be a skilled assassin in a black ops program. All of us that devoured the first four books in the series are totally happy to read of his superhuman skills and gulp them down without flinching. If Evan really has to go, maybe Gregg Hurwitz can invent a new hero? Meanwhile, even though this can be read as a stand-alone, you'll have the most fun by starting with #1, Orphan X (2016). And, of course, each ending is complete on its own - never a cliff hanger here.
