For nightwing honestly I recommend new 52 nightwing run its pretty solid and for Robin you could read detective comics reboot run that has just about all the bat family in it

Well, what have you read?

Batman: Year One, The Knightfall Saga, The Long Halloween, and Batman: Hush are all great jumping on points if you haven't already read those.

@Tupka217 like 1 comic and it was Batman son of the demon

Oh and a robin comic online that is to be continued for me and it had to do with shotgun smith pulling over tim drake as robin at the end
