"My Sister Is a Monster" is a tale of an older brother coming into terms with a new addition to the family; a family who is oblivious to the little monster living under their very roof.
Between all the kicks, screams, weird smells, and messes, this brother comes to find a new friend who he can go on all kinds of adventures with.
And before he knows it, apprehension and even fear turn into what this story is all about: unconditional love.
