There is no particular book on the subject. In general however attachment with family is rooted in the physical consciousness and hence quite difficult to drop off. Still by practice it becomes possible as we start keeping an inner distance. However this often generates suffering in others which brings its own undesirable reactions especially when parents and siblings are concerned. A simpler way is to connect with their best part and for the rest keep moving towards your true goal. Debates discussions arguments do not help. They only complicate relationships.
