Well, this time not TG, but LGBT. I was feeling a little nostalgic so I want through my manga/yuri library and found almost forgoten jewel: yuri manga Pieta by Haruno Nanae. It ´s psychological manga about loneliness and finding your way. It ´s great, touching, and also tough. So make sure you have tissues handy!
For those who want always more, there is loose continuation name Double House, also to be found on http://www.lililicious.net
Online version for reading can be found here: http://www.mangahere.com/manga/pieta/

Here is little teaser:
"But don ´t you think it ´s strange? Two girls, one who wasn ´t loved at all and one who was loved too much, met. They were born in different years and places, but they somehow ended up in the same class at the same school. More than being coincidence, it ´s like someone worked frantically to coordinate their fate. For the sake of present time."
