Indigo's Demons — Sofi Croft

Where darkness hides ... Indigo's life is out of control. He has grown wings and can breathe fire, and fears he may be turning into a dragon altogether. His grandfather has gone, leaving behind a sanctuary full of monsters that are becoming increasingly dangerous, and although his uncle has arrived to help, Indigo begins to suspect that he is keeping secrets from him. Unsure of what else to do, Indigo goes in search of his friend, Rue, hoping she can help, but instead he finds a castle full of demons - ruthless killers that may be more dangerous than anything in his life, yet encountering them may help Indigo understand himself.
