John reconnects with his family

Hi all,

Any help would be greatly appreciated...

SPECIFIC FIC- John receives a letter from a guy who turns out to be his dad's girlfriends son. The lady wants to get married but Patrick won't propose without John there, it's slowly killing the relationship, and the son wants to fix it. John ends up exchanging letters with the whole family and getting a care package. In the end he goes to earth for the wedding injured.

GENERAL FIC- Any good Sheppard family fic:-)

Please and thank you!
