Character Leads to Plot--Part 4

The climax of the book is the event which makes certain whether the protagonist wins or loses.

The climax should also be the event in which the emotional change of the protagonist finally connects and there is no turning back after that.

The climax should reveal the full growth of your protagonist. The world should have opened up, and the rising stakes allow the protagonist to become larger and more important than ever before.

The climax must hold within it the possibility—nay the likelihood—of failure. And yet it must move forward inexorably.

And don't forget that after the climax, there must always be a resolution, at least one scene which shows the protagonist in her new place in the new world, at peace once more (as at the beginning) at least for a moment before the next chapter in her life begins.
