May I recommend the horribly titled:
"The Manipulative Child: How to Regain Control and Raise Resilient, Resourceful, and Independent Kids"
by Ernest W. Swihart Jr.
Note, 'manipulative' here isn't used in the 'conscious/deliberate bad behavior' way, but in the psychological 'attempting to change your environment in order to avoid something or obtain something.'
It's been recommended on this list before, and while it's not specifically about gifted children, their propensity for perfectionism and fear of failure makes it especially relevant. It also made us feel like we'd definitely made some wrong turns with our own DD.
