Re-Education and Reconnaissance - Michelle Rivera - Bog

When the five heroes return home after their triumphant defeat of The Dictator, an era of peace enters Compositora, the capital of the magic world. The residents of the town are finally able to live their lives freely; to wear the clothes they like, eat the foods they want, and have the space to enjoy their freedoms. As the color begins to return to the area, everyone believes the worst times are behind them.
No one could have guessed how wrong they were.
With no warning, the small town is beset by a horde of mysterious creatures that appear every night; not quite human, but not entirely inhuman either, they can only be stopped with daylight, or if they're killed. Their only goal appears to be destruction of the town, liberated just months ago.
The Resistance fights valiantly, but even with the determination they have from finally tasting freedom and refusing to let it go, they quickly find their backs against the wall; and it seems that even the goddesses agree, for they once again call for the aid of ordinary teenagers on earth...
