From publisher blurb:
Death Stalks the Shadows!
Legendary Hybrids: Kinetic Shinobi is the latest volume in our series of class-focused player supplements, introducing a new series of hybrid classes like those in the Pathfinder Roleplaying Game Advanced Class Guide that blend the core elements of two different base classes into a unique synergy all their own. The Kinetic Shinobi brings you a 20-level hybrid class that combines the mastery of mystic and martial arts, bringing together the energy-channeling kineticist and the shadow-stepping ninja. Wielding power and might with the power of the mind, from base matter of the elements to the unknowable depths of the void, the kinetic shinobi is an agile and athletic adversary, flitting and fighting from every direction with hand and blade while gathering in her power to unleash upon every enemy, then disappearing into the shadows leaving silent destruction in her wake.
