The Seventeenth Year: The World Walker, Book 3 / Ian W. Sainsbury

What if every choice you ever made had the power to reshape reality?

Joni, the daughter of World Walker Seb Varden, has never met her father. And the world he left behind has become a dangerous place for the last generation of Manna users. Mee and John insist Seb will return, but what if they're wrong?

Could it be possible she has none of Seb Varden's powers? Or might her abilities reveal themselves as she leaves childhood behind? In her 17th year, Joni will be forced to leave those she loves, face a great evil, and finally learn the truth about her father.
