Home is where the heart is. Or maybe the pizza. There's no better feeling than being back home after a long week exploring the galaxy, though being abandoned by one's friends and left to fend off a glitching evil robot spoils it. All that's left is to settle back into life, preparing Marcy's wedding and job hunting. If only mysterious midnight SWAT teams and crop-circle crafting-sessions weren't constantly getting in Sally's way. When an old foe returns and Sally is the only person on the planet to recognize it, it's up to her, her sullen ex, and an overly-excitable FBI agent to save the planet. But first, they have to get the president safely out of his favorite sushi bar without starting the war of the worlds. It's hard maintaining a long-distance relationship when your crush is light years away and thinks you died of old age, but that hasn't stopped anyone yet. Sally must save the planet, the universe, and herself - though maybe she'll take a nap first.
