Apparently no one has recommended the most obvious, the most important and essential book of all time (past, present and future):

The Bible, the word of God, breathed out by God Himself

There you'll find the instructions on how to become the the best dad ever and, most importantly, you will point your kids to the best gift they can receive, which is eternal life in Jesus Christ

Bonus recommendation:

Successful Christian Parenting, Part 1 of 3 (Selected Scriptures) by John MacArthur
