I don't have much information to go on. Someone I know read this book in 2010, and we're trying to figure out what it was.
Here's what we know remember:
There is some alien influence involved, but it is not necessarily a direct conflict with them.
The lead protagonist is a male. At one point he enters a shopping mall and sees mannequins but he calls them white statues
There is possibly a sickness element too.
This was read in school in 2010
Sorry, I know this is REALLY not a lot to go on. But would appreciate an attempt :D
