Don't Turn Around

This is a reasonably compelling teen hackers novel with an annoying open ending.

He was sitting in the computer room at the Boston Public Library. The fluorescent lighting was dim, barely aided by late autumn light filtering through the large windows. The computer was at least a decade old, some no-name model they probably sold at Radio Shack.

As if!

Also, the title and cover are too dramatic for the content. I wonder if they were stolen from a book that ended up getting cut.
