You definitely need to read Ender's Game! I haven't read Divergent but I've heard about it and read the Hunger Games, you will love Ender's Game mostly likely if you like The Hunger Games and sci-fi! There are aliens none as buggers who are launching a second attack on Earth, during the first attack the human race was nearly wiped out but Mazor Rackham miraculously saved them because they communicate telepathically and the queen is sort of the center of this, he killed the queen bugger. Anyway, Earth is preparing for another attack. There is this boy, he's six at first and his name is Andrew but he's called Ender. He is very intelligent, he has an older brother Peter who is ruthless and violent, he wants to kill Ender. He has an older sister, Valentine who is intelligent but mild. Anyway, it's sort of against the law to have more than to kids so Ender is a third. The government told Peter and Valentine's parents to have a third because Peter was to ruthless and Valentine was too mild, so they wanted Ender to be half and half. Anyway, their plan succeeded and Ender is taken to battle school at age 6, he is a genius and so he becomes a commandor and stuff at a young age, I won't tell you anything more but it's basically all about his time at battle school and stuff. It's so good, sorry this might be a little confusing but seriously read it!
