From Amazon:

A world shrouded in lies, betrayal, and corruption. Warring factions that back-stab and kill to rule. Creatures that can shift forms, stones that hold secrets, and a young boy swept into the midst of it all.

Welcome to Earth. This is the world outside your front door you’ve been ignoring.

Theo Novak always hoped for something to make him special. Friendless and ignored by his peers, he finds comfort in online chess and his fantasy novels. But everything changes when he transforms into a beast in one of the busiest cities in the world, and a mentor and rescuer appears to show him how their world really works.

At last, Theo seems to find his purpose and belonging as a shapeshifter working for a secret international organization.

But is he fighting for the right side?
