It's been a while since King has written a book this good from start to finish.
The story follows Jamie Morton, whom we meet as a young boy and he finds his life interconnected with a young pastor named Charles Jacobs with a fascination for the power of electricity. After tragedy strikes the young Jacobs, he understandably loses his faith and leaves town but the lives of Jamie and Charles will be intertwined from that time on. Jamie grows up to become a musician who succumbs to drug addiction, while ex-Pastor Jacobs goes on to experiment with the "healing" powers of electricity. Jacobs believes he can heal a variety of conditions and his experiments grow larger and more daring as his life goes on, but as Jamie gets drawn back into his old pastors's life, he begins to learn that the cures Jacobs performs come with consequences.
The story moves along quite briskly and there's no wasted time with unnecessary narrative as a few of the last King books have been guilty of (except Under The Dome). The narration is understated and laid back - the only thing that threw me at the beginning of the book was that the narration is performed by an older man - until silly me realised the book was written from the perspective of an old man.
What makes a great Stephen King book is when you read a scene and you can imagine King sitting at his computer grinning evilly at what he has just typed. There's a few of those type of scenes in Revival, my favourite being a re-worked version of Happy Birthday sung to Jamie in a dream. Something happened!
I liked that the "bad guy" of the story, Charles Jacobs isn't the stereotypical villain. He's a man beset with tragedy while only a young man, and while he cynically "preys" on the gullible to fund his lifelong experiments with electricity and healing, its in order to find out the answer to one of life's great questions - what waits for us after death.
For me, what's revealed at the end of Charles Jacobs' quest is where the real boogie man of the story had been waiting for us all along.
