She may not have the sweetest of natures, being spoilt, temperamental and often downright moody, but what twelve-year-old Agathea Fulstropp (Thea to her friends), does have is a rather unusual secret - a secret shared only by herself and her grandfather.

She is Earth's first and only pupil to be enrolled at the Firestone Academy on the faraway Planet of Aruuliah!

Preparing for a new term, packed with the excitement of making new friends, confronting old enemies and getting to grips with alien technologies, Thea is soon to discover that being from Earth has its drawbacks as she becomes the target of a sinister plot to remove her from the Academy - permanently!

Help, however, comes from the most unlikely of places and she, unwittingly encounters a hidden realm concealed within the grounds of the Academy - a world made up of pure energy, populated with mythical creatures of legend and folklore, and whose existence remains a closely guarded secret from all physical beings, whether human or alien.

Time is running out though, as Thea, along with her best friends Jojan and Annalije, desperately try to figure out who, amongst her peers, hates her enough to wish her gone.

Can they solve the mystery before it's too late, or will Thea, having faced mortal danger once already the previous summer, be lucky enough to escape, unscathed a second time?
