Lilly-D Royal Gesh of Seairland, Book 1: The Ring of Yishi (Paperback) (ISBN-13: 9781069733108)

Instead, she got attacked by aliens sent by an intergalactic warlord who wants to rule the universe. Awesome.

Lilly's twelve. Too small. Too stubborn. Definitely not a hero. But when space invaders try to take over Earth, they overlook one thing: Lilly-D doesn't like bullies.

Now she's caught between killer robots, battling factions, and science so dangerous everyone wants it-and no one should have it. With one loyal friend and a bunch of sketchy allies, Lilly has to figure out who to trust, how to stay alive, and maybe stop a war that could unravel the universe. No pressure.

Just one girl, some alien tech, and a very real war.
