Strands of Time (Aeterna Chronicles Book 1)

Seventeen-year-old Kallum is no hero. He wants nothing more than to win the heart of the girl he loves and lead a normal life. But life has other plans. When he loses his guardian, he fears he’s turning into a Crazy. Worse than this? He might just have caused a fracture in the Levitor city's dome, and the threat of invasion looms.
