This story broke my heart. Stories about broken families and spoiled relationships have always struck me, perhaps because so many of my friends growing up were children of divorces, while my parents soldiered on in a marriage that didn't seem - to me - to do anyone any good.
That said, I've always found it hard to sympathize with the character who leaves his or her children in order to "find" himself or herself. My attitude has always been that once you have kids you have an obligation to find yourself right where you are. Wives and husbands you can leave, but kids own you.
That said.
I really felt for Lucian, and understand why he had to leave. He had no idea who he was, what he was, or how to love. It's a tragedy, and his journey towards, away from, and towards human self-awareness was poignant and striking. I like that Eros, Philia, Agape ended on a positive note. I like to envision that as the future the story was headed towards, but I can't let myself forget that the story was definitely presenting it as a possibility, no more and no less.
Oh, and by the way? I thought Rose's reaction to her father's disappearance was incredibly, breathtakingly, sad. More importantly, it was basically realistic, despite the unrealistic context. The rest of the story was really great, but this is the moment that jumped out at me and said "this author is really, really talented."
