Stone of Shadows. Stories of Gereon, #1

In the slums of Gereon, sixteen-year-old Will struggles to survive and keep food on the table for his siblings. Working each day in the fields, he endures regular torment from privileged bully Tristan Arrington. But when a dragon snatches Will, he discovers a stone that grants him the power of invisibility. Returning to the city, Will uses his new ability and stumbles across a much darker truth about Tristan and his powerful father.
Suddenly, the world is no longer black and white. There are people who are much more dangerous than Will ever thought. As a tentative friendship forms amidst a web of secrets, one boy's life hangs in the balance-and just how much of himself is Will willing to risk? This novella contains some darkness and violence, a generous helping of hurt/comfort, and a healthy dose of stupid boys. The book contains an LGBT romance.
