Meet Abriana Yeo, 13, awkward and friendless. Meet Octavia Wu, a graceful teenage alien with superpowers. Forced to flee her home planet Viridis after an invasion by "The Others", another alien species, Octavia and her parents crash-land in the Singapore heartland.

Pretending to be a foreign student, Octavia enters secondary one and befriends Abriana, who then helps her in her quest to find the Anteris, a missing element the alien family needs if they want to return to Viridis to help in the war effort. All the while, the two girls also need to navigate the intricate web of teenage drama at Bukit Timah Secondary Girls' School (BTSGS), where mean girls thwart their search efforts every step of the way.

Behind the adventure, mystery and sci-fi, this middle-grade novel also explores the pertinent issues that teenagers typically deal with in a local school setting—friendship, loyalty, CCAs, homework and bullies. There is also no shortage of excitement and intrigue in this sci-fi and adventure. This is the first in a four-book series, for children aged 10 and above.
