First time dad

Does anyone have any first time dad books they recommend? me & my husband had a very deep conversation yesterday.. he got so emotional because he says he is scared for baby boy to come because he feels like he won’t be a good dad.. he never had his dad growing up so he feels like he doesn’t even know how to be that father figure.. he is beyond excited for the baby but just feels so emotional.. i wanna gift him a book that can maybe ease his mind & just prepare him..
