Eleven-year-old Stella Rodriguez finds herself in possession of a strange new pet that swallows up everything in sight when a black hole decides to follow her home from NASA one day. Stella especially likes it when Larry swallows up items that remind her of her dad who died recently and left a cosmically vast space in her heart. Stella, her little brother Cosmo, along with the help of their pet hamster Stinky Stu and Larry go on an adventure from their clawfoot tub to rescue their dog from the black hole.
