I want Cesar’s dad so bad.
Oh, I'm reading the novel now, but I have not ran into mention of this yet. This is sad if this true, but if she is dead, I'm assuming it was because of a mafia dealing gone wrong, or someone put a hit on her or something. The mom has never been present in any of the flashbacks into Caesar's childhood, so I'm assuming she passed away when he was very young.
Boy moms really need to be stopped
