Final answer:
Lev's kind of unwinding in Neal Shusterman's "Unwind" is called a "tithe", which is a form of organ donation where a child is raised specifically to be unwound as a religious sacrifice.
Step-by-step explanation:
Lev's kind of unwinding is referred to as a "tithe". In the dystopian novel "Unwind", by Neal Shusterman, unwinding is a process whereby a child's organs are transplanted into different recipients.
This is a controversial form of organ donation that is central to the book's plot. A "tithe" in this context is when a child, often raised for this purpose, is willingly given up by their parents to be unwound as an act of religious sacrifice.
Lev is a character in the novel who has been raised as a tithe, and he faces moral and ethical dilemmas regarding his role and purpose.
