Blue Spell. The Cirrus Chronicles, #2

There's no such thing as magic. But that doesn't mean we can't use it. Jack Scatter knows that the mysterious force he wields has a technological source, and so does the man who's trying to kill him. But he'll need to tame dragons-both real and psychological-to harness that power to save himself and two worlds. Jack and Sarah should be in high school, enjoying their senior year. Instead, an apocalyptic event interrupts their summer vacation and leaves Cirrus-the world-sized space station they live on-without phones, internet, or transportation.
Sarah gains the ability to see the future. Jack gets a magic wand and an arch-enemy who can control people's thoughts. Wormholes used to be as common in Jack's world as electrical outlets in ours, until Pieter Reynard discovered a way to destroy all the portal crystals on Earth and Cirrus at once. Now, Pieter has plans to rebuild those crystals and cast himself as the hero of the recovery. But his crystals have a dark facet, and he'll have unlimited power and control unless Jack and his friends stop him.
To do that, they'll explore "magic" and create "spells", and Jack will have to overcome his lifelong anxiety in order to use Pieter's talent for manipulation for a better purpose. BLUE SPELL is a YA adventure that blends Science-Fiction and Fantasy.
