Something strange is afoot at the library.

Seventeen-year-old Sadie isn't feeling so great. She's not sure if it's something she ate, or if it's from flipping through one too many teen paranormal romances, trying to find inspiration for a creative writing assignment. But she's determined not to barf in the vampire book she's holding, especially not in front of the cute guy who's checking out the library's pitiful selection of DVDs. So she makes a run for the bathroom... only to have the guy follow her in. She is not amused.

When they emerge, the library appears to be closed. Weirder still, it's surrounded by an eerie supernatural storm that definitely wasn't there a few minutes earlier.

Being trapped in a library with a new friend (or enemy—Sadie hasn't decided yet) might not be the worst thing in the world. But it might not be the best thing, either... especially once that weird storm starts spitting out characters that are only supposed to exist in stories.

It's turning out to be one weird night at the library. If Sadie and Lincoln want to survive it, they'll need to figure out how to take on a horde of zombies with nothing but their wits, the Dewey Decimal System, and some very strange bookish magic.
