The Rip's Mark by R.S.K. Archer

Our world has a rip. A rip through space itself. Finally old enough to attend the prestigious Academy in Cambridge, Indigo is excited to fulfil her lifelong dream of becoming a guardian of the Rip, just like her mother before her. But making friends when everyone seems to have a hidden agenda is harder than she expected, especially when it comes to her frustratingly handsome training partner, Kriger. Thrust into a world of corruption, deadly games, and broken trust, her dream begins to unravel before her eyes, and Indigo is left wondering whether she will make it out alive.
