Cassian Voss was raised in an old military family built on generations of power, violence, and inherited wealth. Cold, feared, and dangerously controlling, he now leads a powerful private military organization with the same ruthless discipline he was raised under. Despite his harsh nature, however, Cassian is obsessively devoted to his blind husband — a calm, gentle, and physically fragile man who suffers from chronic health problems and depends heavily on routine, medication, and care.
