ParentSpeak is a provocative guide to the hidden dangers of “parentspeak”—those seemingly innocent phrases parents use when speaking to their young children.

Imagine if every time you praise your child with “Good job!” you’re actually doing harm? Or that urging a child to say “Can you say thank you?” is exactly the wrong way to go about teaching manners?

Jennifer Lehr is a smart, funny, and fearless writer who takes everything you thought you knew about parenting and turns it on its ear.

Backing up her lively writing and arguments with research from psychologists, educators, and organizations like Alfie Kohn, Thomas Gordon, and R.I.E. (Resources for Infant Educarers), Ms. Lehr offers a conscious approach to parenting based on respect and love for the child as an individual.

Ada Sibelius is raised by David, her brilliant, eccentric, socially inept single father, who directs a computer science lab in 1980s-era Boston. Home-schooled, Ada accompanies David to work every day; by twelve, she is a painfully shy prodigy. The lab begins to gain acclaim at the same time that David’s mysterious history comes into question.

When his mind begins to falter, leaving Ada virtually an orphan, she is taken in by one of David’s colleagues. Soon she embarks on a mission to uncover her father’s secrets: a process that carries her from childhood to adulthood. What Ada discovers on her journey into a virtual universe will keep the reader riveted until The Unseen World’s heart-stopping, fascinating conclusion.
