John Dies @ The End by David Wong

Profane and hilarious, this book is like a mashup of "Ghostbusters" with "Bill & Ted's Excellent Adventure." Humanity is in peril as portals to another dimension open and spit through evil beings, and the only ones (maybe) able to save us are a pair of twenty-something slackers.

David works in a movie rental store, and John can't keep a job for more than a couple months. At a summer party where John's (horrible) band plays, a new drug gets passed around. Nearly everybody who takes the "soy sauce" dies in a dramatic and horrific way - except John, who goes comatose.

Turns out the drug turns your brain into a supercomputer able to do astronomical calculations of probability in a split second, and allows you to see horrific and fantastic things invisible to everyone else.

This book is incredibly smart - and also really, really dumb. It's twisty and unpredictable, funny and fun, but not the kind of thing that will last long in your memory. Sometimes you just need a good flight of fancy, and this one has certainly been entertaining for me.

There is a sequel, and I will be looking that one up too.
