The Hidden Enemy — Zack Satriani

When insectoid aliens attack, three kids from different planets must work together to save their universe.

Dray is a born warrior who kicks major butt, but her father dismisses her because she's a girl. Keller can hack any computer and pilot any spaceship but his smart mouth gets him into trouble, especially with Dray. Ayl has only known the safety and harmony of his underwater world and is in for a rude awakening when he ends up with a kinetic shotgun in his hand, facing down a hive-mind insectoid alien that wants to eat him.

Fast-paced with cool gadgets, this accessible action-adventure will thrill fans of Dr Who and Star Wars.

This is the first book in the series: read on with THE ASSASSIN and THE INVASION.
