Christina Herald was my favorite until Alex came along. But I have to wonder if this is biased by the fact that I was cooperating with Christina's author, and now coordinate with Alex's. Nevertheless, I enjoy Alex's antics, sympathize with his anxieties, and find him quite real. He bounces from problem to problem, never letting me get bored but never seeming contrived, either. I feel like I could relate to him, if we knew each other (or maybe I just wish I could, trying not to lose my youth). I do have something in common with Sharon, though, and I'm watching her progress intently.
