Part Four

Rate this book
Maggie has discovered the world is a giant, marooned star-ship—and the gnomes have been running maintenance while humanity napped.

Now those pint-sized engineers are split into two warring crews, both convinced they should be in charge of the engine room. Worse, Simon’s rogue faction is waking ancient goblin hordes to hijack the ship and steer Earth straight into oblivion.

Chosen by the legendary Magic Compass, Maggie’s “peabrain” switches online, revealing the elemental power her father once wielded. One minute she’s trying to remember where she left her shoes; the next she’s hurling tornadoes down vine-choked corridors with a sarcastic gnome wingman and a knight who still hasn’t mastered indoor voice.

The clock is ticking, the ship is groaning, and betrayal lurks in every air vent. If Maggie can’t unite the feuding crews and master her brand-new Elemental skills, humanity’s cosmic cruise ends here—no refunds, no lifeboats.

Laugh-out-loud banter meets pulse-pounding adventure in the explosive finale of Peabrain Part Four. Hop aboard, buckle in, and hit Buy Now to join Maggie’s last, wild ride!

exciting end of this saga

Maggie and her group of Elementals have to find the steering and engine rooms to fix the ship before anything else happens. Along the way they have quests that challenge each Elemental, but the others have to help and need to go through them too. They encounter unexpected enemies in places they didn’t know existed. Satisfying ending to series.
