Final answer:
The ultimate boon in "A Wrinkle In Time" is the defeat of the Dark Thing, the rescue of Meg's father, and Meg's personal growth and acceptance of her unique ability to love, which she uses to overcome evil.
Step-by-step explanation:
The ultimate boon in "A Wrinkle In Time" refers to the climax of the protagonist's journey where they achieve the main goal that they have been seeking. In the context of the novel, this boon is the defeat of the Dark Thing which represents evil, and the rescue of Meg's father.
It symbolizes hope, love, and the power of goodness and individuality in the face of overwhelming darkness and conformity.
In her adventure through time and space, Meg Murry learns the importance of embracing her own faults and using love to overcome obstacles. The concept of the ultimate boon is deeply tied to Joseph Campbell's monomyth or the hero's journey, which involves stages such as departure, initiation, and return. The ultimate boon typically occurs during the return phase, as the hero triumphs and brings back something of great value to their society or to themselves personally.
In "A Wrinkle In Time", the ultimate boon is not just the freeing of her father, but also Meg's inner transformation and growth as she realizes that it is her own unique qualities, including her ability to love, that enable her to succeed where others have failed. This empowers her to vanquish the antagonist, IT, and restore harmony to her family.
