So you have your single sentence to describe your novel? (See, Tiam? I started a sentence with "So...")
Part two involves E X P A N D I N G that sentence into a small paragraph (which will end up sounding a bit like a back cover blurb):
Sentence #1 Story setup / backdrop
Sentence #2 Conflict / disaster #1
Sentence #3 Conflict / disaster #2
Sentence #4 Conflict / disaster #3
Sentence #5 A HINT of the ending or resolution--don't give anything away...
Keep in mind that this is a GUIDELINE, and I won't be counting sentences, or anything like that. Just be sure to have the five parts covered:
Blake Mack is a thief who, while fleeing police, veers off onto a logging road and slams into a cyclist, whose identity he assumes. he enjoys his new start at first, but then a young hotshot police officer with something to prove starts making his life more difficult. To make matters worse, he discovers a shocking secret about the true identity of the man he has become. when a new love interest betrays him, he has no one to turn to. He's on the run--from the law, from "The Company," and from a broken relationship; his only way out may be to start all over again...will he get the chance?
