Spellkeeper Flight boxset (The High Road, Freefall, Grounded). Spellkeeper Flight

When you can fly, don't look down. The enemy's above you. Enter a world of gangs, high-flying heroism, and magic that can transform lives or shatter them - in the complete Spellkeeper Flight trilogy. Mark has never been the survivor his friend Angie is, but when he rescues a mysterious belt from the flames, its perilous secret changes their lives forever. As the two tap into the power of gravity-controlling magic, they discover the reason Angie's family tried to destroy the belt.
Leaping into the sky is as dangerous as it is breathtaking. The battle begins with a street gang stalking them for the magic's secret, but those killers aren't the only ones watching. Enemies hide within the minds of friends... nature twists to protect its ordinary-seeming master... unsuspecting people struggle to control the magic they've stumbled into. A single shape falling from the sky can shatter someone's world.
This is Ken Hughes's complete Spellkeeper Flight urban fantasy series. Follow the journey's every joyous leap to the clouds, every sinister twist, every desperate choice made as different allies and enemies reveal just what they'll truly fight for. And the one unshakeable bond between two people that is stronger than a world of magic.
