After May’s tragic death, what is the tone of the incidents that follow in this chapter?

I think that the tone turns sad but reflective. August finds May’s suicide note. May apologizes for leaving them in such a manner, and she says that she is just too tired of carrying around the weight of the world. She adds that it is her time to die, but it is June’s and August’s time to live. She encourages them not to mess up their chance. August interprets the note as an encouragement to June to marry Neil. June seems to take this advice to heart, and she thinks deeply. Zach, Lily, and August undrape the hives, and they begin to feel more comfortable with the idea of saying goodbye to May.
