There is an upcoming
Hawaii Five-0 holiday fic swap.
to quote, _Authors who sign up will receive a secret assignment. They will have eight weeks to write a story of at least 1000 words for their recipient (there is no maximum word count). Everyone who signs up will have a story written especially for them and will in return write a story for someone else. Fics can be posted directly to the community or posted in your own journal and linked back; submission details will be available closer to the posting date.
Signups go live in the last week of September. _
