Hmmm... I can't personally vouch for any of them. All I can say is that out of those 100... I would be tempted to buy:
I Am Legend by Richard Matheson
Ex-Heroes by Peter Clines
County Line by Bill Cameron
and possibly
Skellig by David Allmond
That's not based on any empirical data, though. That's just browsing and saying; "hmmm, that looks kinda cool" (with the exception of I Am Legend... which I've always intended to read someday).
