What is the girl with all the gifts ending?

"The Girl with All the Gifts" is a post-apocalyptic horror novel written by M.R. Carey, which was later adapted into a film in 2016.

In the ending of the novel, the main character, Melanie, who is a young girl with a special gift and a form of symbiotic relationship with a type of fungal infection that has turned most of humanity into mindless zombies, finds herself faced with a difficult decision.

Melanie ultimately chooses to sacrifice herself in order to save the remaining survivors, including her teacher Ms. Justineau and the scientist Caldwell. She allows herself to be captured by the military and is taken away to be dissected in order to find a cure for the infection.

The story ends with a glimmer of hope, as it is implied that Melanie's sacrifice may lead to the development of a vaccine that could potentially save humanity from extinction. The ending is bittersweet, highlighting Melanie's selflessness and the complicated moral decisions that arise in the face of seemingly insurmountable odds.
