I waited the whole week for Sunday to come so that I could finally rec this fantastic series. It is like nothing you would suspect if you read its title.
The story is certainly not a kid-fic, but maybe you could call it a case-fic. Perhaps even Sherlock & Johns biggest and most personal one.
Start with "Crazy for love" an exciting journey into an amazing and believable AU of season 3 and continue your adventure with "Risk of Absense".
You will not regret it.

Nothing fluffy about that series, but that doesn't mean just darkness and dispair.
It is life. The ups and downs. The curve-balls it throws. The finding something unexpected. A missing piece.
It is really plot heavy. Just how I like it. And it is difficult as hell to rec it without spoilers.
It feels real.
