I have just been sent a story by Elizabeth Stephen about Elros and Elrond called The Choices of the Peredhil , which is very powerful, but at 14 pages, a bit too long for the Forum. (Anyone who would like to read it email me at email@example.com and I'll send it.)
This has inspired me to suggest a Theme for the Summer - up to September - of Siblings.
This could be in first or third person, could refer to any siblings in Tolkien's corpus - and could be stretched to cousins if you wanted to do Hurin and Huor, or Turin and Tuor - and can be prose or poetry and as short or long as you wish.
I hope someone might have time during the Summer to create something for us all to study and enjoy.
