In this world there are a group of girls who call themselves Star Sisters who are 14 to 18 years old physically. They have the power to transform living beings or objects into any other form of living being or object and to alter people's perception so they think a particular transformation is normal or has always been that way. If they transform a living being into some type of inanimate object that being's soul will be in the inanimate object able to feel, see, and hear. They can transform inanimate objects into copies of living beings but those copies have no souls or life in them. They can create portals through which they can travel through. People don't notice these portals or anyone coming in or out of them unless the Sisters want them to. They can not affect free will or the mind with the exception of altering perceptions.
They are born as both boys and girls with a birthmark on their genital area. This birthmark can be in any shape but once their Star Power activates, can be at any age, it transforms into a star shaped birthmark. Depending on their age that will be the only transformation those born as girls will go through. Those that are older or younger will of course change their physical age. Those born as boys however must undergo a sex change as well.
Michael and Jane Starr are guardians for the Star Sisters and they have taken their last name.
Now someone is about to become a Star Sister. Who is it though?
