"Dark Matter" by Blake Crouch - I've never heard of the guy, but apparently his "Wayward Pines" trilogy was made into a Fox series, and now I see Yappi had a thread on this five years ago.
A Chicago man, who leaves his wife and son to run a short errand, is kidnapped by a strange man and drugged into unconsciousness. When he wakes up, he's in a Chicago he doesn't recognize, surrounded by people he's never met but who claim to know him - and now the woman he's known for 15 years as his wife tells him he broke off their engagement to do research, so their son was never born .....
I was hooked by the plot, takes the doppelganger concept to a new level. I even understood the gist of most of it. Rod Serling and Stephen King would be proud.
Crouch's writing style is a bit irritating. He does a lot of "bullet point" writing, where he describes the contents of a room with one-word sentences and hard returns, instead of making a longer sentence or paragraph. I guess it's supposed to be a starker, more impactful style. Not quite my cup of tea.
Anybody read Wayward Pines? Gonna check it out when this madness ends and they open the library back up, at least for on-line reservation and pickup.
