i think its a good idea that Fred got to fall in love with someone :) but i dont think it will be Leah tho i cant see a vampire and a werewolf falling in love (and jake and nessie dont count shes half human :P)
i would love a fred book :) i hate not knowing what happened to him when he left bree, i think it would be interesting.
he could even somehow find the cullens and join them :) that would be pretty cool.
ohhh he could fall in love with Tanya!!!!!!! how awsome would that be? :)
