Been reading through Suicide Island the past couple of days and I'm finding it pretty gripping. Unable to cope with the fall-out from rising suicide rates, the Japanese government gathers those who cannot stop attempting and ships them off to a deserted island, leaving them to get on with it. Although some carry on trying to take their own lives, others slowly regain their will to live and try desperately to survive.
With its leering moments of horror, it's almost certainly influenced by the first season of Lost (y'know, the good one), but there's something oddly thrilling about seeing the main character gradually find meaning to his existence as he experiences a weird commune with nature.
I've read about half of what's been translated so far and, while there's still plenty of meat left on its bones, I'm kind of hoping that the story might draw a conclusion fairly soon. It would be great as a compact little thriller, rather than becoming bloated and drawn out (like the later seasons of Lost)...
