The Man from Primrose Lane by James Renner

I was eager to read "The Man from Primrose Lane", so eager, in fact, that I read it in a single day. I loved the first 3/4ths of the book, which was a compelling blend of mystery and thriller with a subtle thread of sci-fi sneaking around in the shadows. And then . . . ah, and then. Then the book hit a wall and turned 100% into a sci-fi novel, and not a very good one. Essentially it was two different books, pasted together under the same cover. Sadly, I have to give this a C at best.
