I also loved the idea behind 'Inertia' by Veronica Roth; to mind-meld with someone and share memories while they are on the edge of death. There were really so many well-crafted love stories, all different in their own interesting concept. They all tied together in that they reflected some form of love or romance, but at the same time they felt separate and important in their own ways.
I recommend reading both anthologies if you are a fan of young adult literature and love stories (both romantic and unconventional). And yes, some were more realistic, in terms of being about love that ends or does not quite go as "Hollywood" as most love stories would. It was not all bubble gum, unicorns and rainbows (although, a couple were).
