The Shapeshifters Book 1. The Shapeshifters

A city teeming with life and vibrancy, lies a secret hidden beneath the bustling streets. Beneath the surface, a community of extraordinary individuals thrives in the shadows, each possessing the uncanny ability to shapeshift into any physical form they desire. They are the Shifters, gifted with powers beyond imagination, living a life of seclusion and anonymity, safeguarding their abilities from the prying eyes of the world.
For generations, the Shifters have lived in harmony within their underground enclave, embracing the duality of their existence as both humans and extraordinary beings. They have honed their skills, mastering the art of transformation and unity, finding solace in the understanding of each other's strengths and struggles. However, the balance they've maintained is shattered when an alien ship descends upon the Earth with a malevolent purpose.
The invaders, known as the Dray'eth, are relentless and ruthless, with the chilling objective of annihilating humanity to harvest their skeletons. They seek to freeze the bones and use them as a foundation for new alien bodies, a macabre means of colonization across conquered worlds.
