This is my last prepared #AuthorLingo101. Does anyone want more of these?
MC: Authors, when speaking among one another, tend to abbreviate MAIN CHARACTER to MC, because we're super cool.
HOOK: This can be used in different ways. Sometimes it's a book's premise (centenarian escapes nursing home), sometimes it's about whether those first sentences hook, and it's also used as an adjective (that's hooky) and verb (the premise hooked me.)
