City of the Falling Sky
Seckry Sevenstars is just settling in to life at his new school in Skyfall City when he finds a girl with no memory in the city's largest science research facility.
What is her name?
Why was she there?
Were Endrin experimenting on her?
As Seckry and the girl determine to find out, they realise that some people will stop at nothing to keep what's going on at Endrin under wraps.
