I think broadly, the challenge with parenting books is that they sometimes put forth a particular philosophy or approach (some are more neutral and inclusive than others). So, I think it really depends what you are looking for, what your parenting style is, and the ages of your kids.
And if you are looking for advice, context is really important.
To directly answer though - my favorite parenting book is The Gardner and The Carpenter by Alison Gopnik
