Psycho Therapy by Ryan Hyatt

Action-packed, makes you think

Yeah, I can see an alien invasion going like this. Ryan writes like a comedian, taking an observation on human nature to its extreme, but somehow logical, conclusion. The action starts on the first page and continues until the last sentence while weaving in character development and building a post-invasion America. There's a tie-in to his Terrafide series as well that I'm looking forward to reading.
