The conflict in Legend is "man vs government" because the cupped government is hunting down Day and in the process brainwashing and lying to there soldiers (June/Metias).
In the book Legend, Day brakes into a hospital to steel plage cures for his little brother. In the prosses, he runs into Metias (June's brother)and throws a knife at him but does not kill him but somehow he dies.
When Day gets captured it is a very action-packed and sad at the same time because you think "Day is too good, he can't be captured" and this is what makes it is so sad. It is all so very sad when Day's mom dies.
The climax of the story is when June finds out that Day is innocent and that the government ordered to kill Metias. This is the climax because you know this is the turning point for June.
June teams up with Day and the rebels then makes a plan to break him out.
Both June and Day escape but now all of Day's family is dead.
