Mission Improbable by J.J. Green

The galaxy is in crisis, and Carrie Hatchett is the last person on Earth who should be fixing it.
Carrie is a low-achieving daydreamer. After providing a good home for her butt-ugly dog and psychotic cat, her biggest challenge in life is to avoid being fired, again.
But a strange green mist sucks her beneath her kitchen sink, and an unusual clerical error leads to an offer she foolishly doesn’t refuse.
The Transgalactic Council hire her to settle a conflict between the mechanical placktoids and the mysterious oootoon. Carrie must overcome her personal weaknesses and, for the first time in her life, succeed in her job, to uncover a threat to the entire galaxy.
Mission Improbable is Book One in the light-hearted, fast-paced Carrie Hatchett Space Adventures series.
"...like Scully and Mulder on acid."
