Most loved...
As a kid, Justin Xiang-Allard was a big favorite, but also Candace Liao. No offense to Lara croft who's poster adorned my bedroom, but Candace really radiated something.
As a teen, Sun-Tzu Liao caught my interest.
Here was a character wholly commited to a goal above and beyond himself (in a way, for he too IS the state)...but espescially, here was a character constantly restraining himself, testing himself, trying to "become more" then his lesser nature. Now I guess this won't strike much of a chord with most other readers as what I will reference is little known in the english world (heck, there's no wikipedia article in english on the book!), but Sun-Tzu was heavily reminiscent of the twins in "the notebook", a hungarian novel that was quite popular in some areas. The first tome of the trilogy was fascinating, mostly through the said twins. So yeah, the attractiveness of a character playing on the theme of going beyond one's mere human nature.
Nowdays, I'd say back to Candace Liao. Looking back on the characters story, I can't help but feel how much we've seen a human evolve and how that's interesting. I mean, consider this relatively succesfull officer and mechwarrior. Then the scheming passed-on would-be heiress trying to turn the wolf's dragoons into a personnal army and lashing out violently and out of wanton spite upon the failure of her attempt (probably the first time she was spurned, which is an interesting story in its own right). Then the small time imperatrix and skillfull economist ruling over the national bank of the capellan state. To the women who mellowed through her love affair with the James Bond of the 31st century. An then the wise ruler of the ill-fated St-Ives Compact. To finish her days in a concilitory inner politics peacemaker role. Quite the biography there. Not the most flashy, but offering so many facets.
Most hated...
Well...I strongly dislike Andery Kerensky. I mean, I don't hate everything about him, some parts of the character are interesting...but he just...falls on my nerves. So much wallowing, so much self-pity...
I really liked the first two books of the "foundation of the clans" trilogy. It's a good read and the subject is quite the draw. But I only read the first two back-to-back. When I was set for the last part, I really needed a break from Andery. Haven't read the 3rd book yet. I'll get around too it as soon as I'm feeling the courage to read another e-book in a rapid fashion, it's a the top of my "pulp-fiction to read list"...but if it wasn't for Andery, that book would've been read a long time ago.
I'd like to say he makes me cringe but I'm not sure I'd use the term correctly.
