Corollary (Corollary #3)

After saving the Sentient Moon Modus Ghar's twin brother by enacting the same procedure that saved Andromeda, the body-swapping twins make a discovery that changes everything. The transferring process that enables them to swap between Cass' human body and the ship's life-support system degrades with each use. With only a couple of switches left, the sisters need to make a PERMANENT decision: body... or ship?
