Touchstone

On her last day of high school, Cassandra Devlin walked out of exams and into a forest. Surrounded by the wrong sort of trees, and animals never featured in any nature documentary, Cass is only sure of one thing: alone, she will be lucky to survive. The sprawl of abandoned blockish buildings Cass discovers offers her only more puzzles. Where are the people? What is the intoxicating mist which drifts off the buildings in the moonlight? And why does she feel like she's being watched? Increasingly unnerved, Cass is overjoyed at the arrival of the formidable Setari. Whisked to a world as technologically advanced as the first was primitive, where nanotech computers are grown inside people's skulls, and few have any interest in venturing outside the enormous whitestone cities, Cass finds herself processed as a 'stray', a refugee displaced by the gates torn between worlds. Struggling with an unfamiliar language and culture, she must adapt to virtual classrooms, friends who can teleport, and the ingrained attitude that strays are backward and slow. Can Cass ever find her way home? And after the people of her new world discover her unexpected value, will they be willing to let her leave?

In the months since Cassandra Devlin walked off Earth onto another planet, she has grappled with everything from making blankets to helping psychics battle the memories of monsters. Not able to find a way home, she has instead gained friends and a purpose. Unfortunately, that purpose brings with it the pressure of being more than a little valuable, and those she has befriended are also her guards, ordered to explore and control her abilities to find out just what it is a touchstone can do. Test subject was not the career path Cass had been planning. With no privacy, too-frequent injuries, and the painful knowledge that she must always be an assignment to her Setari companions, Cass can only wish for some semblance of normality and control. And as her abilities become more and more dangerous, tests and training may be the only thing capable of protecting Cass from herself.

Cassandra Devlin doesn't know what she's for. But she knows she's running out of time. Since Cass was rescued from the abandoned world of Muina, the Aussie teen has proven more than useful to the people of Tare. Expeditions to their home world no longer end in slaughter. The teaching city of Kalasa has been unlocked. After years of searching for answers, they are starting to make progress. But space is tearing itself apart. Ionoth attack in ever-greater numbers. And "the useful stray" has been injured so many times that the Tarens hesitate to use her for fear of losing her. With one particular Taren now her most important person, Cass is determined to contribute everything she can, and hopes to find some answers of her own. What is the link between Muina and Earth? Why are the reclusive Nurans so interested in "rescuing" her? And what role in the crisis do the inhuman Cruzatch play? Can Cass keep herself together long enough to find out?
