I beta read a great Big Bang contribution this year
'the art of incubating dragon eggs' by
sa_kun She does a great job with a world building and keeping the mystery alive until the end of the story so if you are looking for a big bang fic to read this weekend, I'd recommend you try this one. There's also great accompanying art. If anyone has any other recommendations, feel free to share, I haven't read all that many big bang stories yet due to a lack of time, so I wouldn't mind being recced a few good ones!
