Janelle Brown's I'll Be You is a shocking thriller about twin sisters and the lengths they'll go to in order to protect one another.

They haven't spoken in years, so Sam is shocked when their father reveals Elli has left her family and joined what may very well be a cult in Ojai. Now it's up to Sam to bring her sister home, even if it means uncovering secrets that should stay buried.
