Whose the Cannon Fodder?

Erica Auburn dies. But that was not the end of it. She finds herself reincarnated as the cannon fodder villain in a novel she just finished and she now has a cannon fodder baby too. How unfortunate...
No! She is not going to settle for this fate. She's going to ditch the protagonist's family and leave the Empire with her newly acquired baby.
However a certain General who woke up from a coma puts an end to her plans.
By the way... Why does the cannon fodder baby call the General 'Mommy'?
