Music of the Soul

I've read a few of these crossovers and I really liked the idea so I wrote my own. Riddick knows River from the Academy and has fallen in love with her but that isn't good for the bad guys so they take him away and tell her he's dead. She can't find his mind and so she believes them. One year later Simon rescues her and they find Riddick on Serenity. Let me know what you think.
