Following Lifehack's nanotech disasters, new laws restrict the development of nanites... ...forcing the hand of dangerous people...

Cassidy needed a fresh start, and the offer of a guard posting for a historic temple in the middle of the desert sounded like a good way to clear her head.
She didn't expect to find a new girlfriend- maybe even a soul mate.

In the years after Lifehack and the Erebus incident, the world settles into relative quiet under strict nanite bans, but underground activity keeps dangerous nano-tech alive and well.

Cassidy didn't expect to be in the crossfire of a terrorist, a cowardly scientist, and a fleet of microscopic invaders. She didn't expect to lose.

(Although Watching Yute is a complete tale within the Lifehack series, it chronologically takes place between Lifehack and Echoes of Erebus.)
