Fade Out

Scarlett has lived all her life being a Jemstale (imaginary friend who provides guidance and watches over children who need her) when suddenly children don't need her anymore she is incompatible
to any more children and with the Jemstale world overcrowding the council is thinking about making it three years instead of thirty before the start putting people who have no cases(children to watch over)in Stan meaning the Jemstales fade out and are never heard from again.The only way she can live is if she finds a kid who needs her or finds her human soulmate.Which will it be?
