A Love Letter to My Daughter by Ronnie Holman is essential reading for today's dads, underlining that 70 percent of kids get their sense of self from knowing that their parents care and are involved in their lives. The book mixes old-school wisdom with new-age sensibilities. It talks about the trust that should exist between fathers and daughters, the joy that should be embraced in this fatherhood gig, and the way that this thing we call "life" should be lived in the presence of our "almost-invisible" daughters with the unbreakable bond that we cherish and never take for granted.
