The second book of the Starters series, Enders, Callie finally can be a normal girl, or so she thinks. While hearing The Old Man's voice inside her head, is she really safe? Worse, she hears her supposedly dead father inside her head as well. Is it her father, or is the Old Man playing a cruel trick? That's not all, she meets a handsome boy who says he's the Old Man's son. Can she trust this boy enough to stop the Old Man once and for all and get this annoying chip out of her head?
I believe this is a rather good book, I haven't read the first book yet, so it was kind of confusing, but the book explains enough for me to get an idea. The characters are well-developed, and the details are amazing. Callie is a strong-willed girl whom everyone will love. She thinks of everyone besides herself, especially her little brother.
