Vassily the Beautiful (The ESTO Universe)

Vassily Belikov, composer and pampered son of privilege, suffered neurological damage in the accident that killed his father. Resentful of being treated as an invalid, he lives as a recluse, dependent on his mother. That changes the day she brings home a new husband with two sons of his own.

When deep-space pirates capture Vassily's mother, he's left to the mercy of his cruel, amoral stepfather. Fighting addiction and his physical shortcomings, he's forced to seek out the criminal mastermind Baba Yaga for a crucial piece of equipment. While she agrees to deal with him if he beats his Exoticus addiction, paranoia and mysterious intentions infuse her household. Drawn to her fierce, suspicious youngest son, certain his actions are all carefully observed, Vassily must find the courage to face both his fears and his desires if he expects to survive.
