I've been on Authonomy for about a month now and I've received some very helpful feedback from other writers on this site. I'm continually revising my chapters, using all the advice I get, and I see improvements already. I hope you'll check out my book, Chameleon, and let me know what you think. I welcome feedback and critiques. I'll be happy to return reads and critiques.
Here are my short and long pitches for Chameleon(http://www.authonomy.com/books/40687/chameleon/):
An overly excitable genius in witness protection struggles with the moral complexity of deception when she goes undercover as the principal of a dangerous school.
Claire Constantine, a professor and former child prodigy, entered the Federal Witness Protection Program (WITSEC) one year ago. Now, after messing up her first two cover identities, she is starting over. She and her three-year-old son are being relocated to Denver where Claire expects to teach math. But the school board has other plans—they expect her to be principal of the worst high school in the city, a school full of delinquents as dangerous as the criminals she’s hiding from.
What Claire doesn’t know is that the board resents her because they were coerced into hiring her. They responded to that coercion by setting her up to fail. When she finds this out, she requests another start-over, but the marshal handling her case refuses to move her again. She has no choice but to stay and try to do her job.
As she struggles to fix the broken school, Claire begins a secret romance with the school superintendent, Steve Jensen. From the start of their relationship, the lies pile up forcing Claire to deal with her qualms about deception. How far is she willing to go? Is she willing to hurt the people she loves?
