Ya'll. This book is SO GOOD. Here's the short Goodreads blurb: "After the 1st wave, only darkness remains. After the 2nd, only the lucky escape. And after the 3rd, only the unlucky survive. After the 4th wave, only one rule applies: trust no one."

This book is the literary equivelant of the best kind of action movie. It sucks you in from page one and stays plugged into your brain even when you're not reading it. It's super quotable, full of snappy dialog (spoken and inner), and some truly great action scenes. But it's got a lot of substance too: it's smart, well-written, with fleshed-out characters and a tight plot. And, like many science-fiction/post-apocolyptic novels, it asks those philisophical and existential questions like why are we (humans) here? What does it really mean to be human? Why do we fight to survive? Should we even bother? And I really can't say enough about these characters: I want them all to come live with me.

Bottom line: if you're in the mood for some smart, heart-felt, alien-invasion-style action, check out The 5th Wave, by Rick Yancey (fair warning: it's the first in a series).
