There is something very wrong with Polly’s new friend,
Gemma, a look-alike Queen Nefertiti, and Polly, who is crazy about Egyptian history, is soon worried about her.
When she is invited to Gemma’s house, Polly suddenly finds herself caught up in a series of terrifying events.
What is it about the Egyptian wall-painting that is so scary? And why does Gemma hate it so much?
Why is there a stone Nefertiti in Gemma’s room?
As Polly comes under attack from powerful and determined forces, she has to outwit these deadly intruders, or become like Gemma.
Can either girl escape the aliens and the future mapped out for them?
