My new step brothers

Rosalyn isn't your usual 11 year old, she is smart really smart
Which is basically what she used when her parents were always gone since the young age of 4 she has been left home.
Since she was deemed bright for her age it was fine but when your young its scary.

After her mother dies her father remarried a woman named Angie, but Angie has 3 sons, so will Rosalyn who has always been a only child be able to handle this
Especially now at 11 she will be entering grade 10.
