My picks, in no particular order...
1.) Liz from Feeling Sorry for Celia - Jaclyn Moriarty is a master of characterization, but I think the one I would most want to be friends with is still Elizabeth from the first book in the Brookfield-Ashbury series. She's so very relatable, struggling with a lot of issues all teens do without once coming across as over-angsty. And she's got a great, dry, subtle sense of humour, similar to my own, that I love. I think she'd make a loyal and supportive friend.
2.) Fflewddur Fflam from The Prydain Chronicles - Because he is absolutely hilarious, I'd always be able to know when he was stretching the truth (oh those harp strings), and he really does come through in a pinch. Actually I'd want to be friends with a lot of the characters from this series.
3.) Mary Quinn from the Agency series - She's courageous, loyal and determined to do what's right and figure out the truth. I think she'd be a bit hard to get to know since she's quite a private person, but I'd definitely want her on my side if there was any trouble.
4.) Suze from the Mediator series - Suze picks her friends well. She's not fooled by all the snobby but nasty girls at her school and instead befriends one who's a lot lower on the totem pole. I like that she's not afraid to say what she thinks and that she respects and cares about her geeky younger stepbrother Doc. Plus, she'd be a good ally to have in a fight!
5.) Areida from Ella Enchanted - I'd probably want to be friends with Ella, too (though the curse-less Ella), but Areida's a side character who doesn't get too much screentime and yet is a fabulous friend. Ella has been pretty alone until she meets Areida, who is also a bit of an outcast at their finishing school. The two girls bond and I always felt sorry for Ella when she is forced to let go of that friendship.
6.) Nee from Crown Duel - Meliara is a difficult person to befriend, but Nee manages to do it. She is sweet, well-meaning and genuine, and although she doesn't play a critical role in the book, she makes Meliara's days at court much easier.
7.) Kate from Sorcery and Cecelia - We are quite similar personality-wise and I always thought we'd get along. She doesn't like huge parties either, so we'd probably just hang out and talk :)
8.) Elinor from Sense and Sensibility - I know, everyone's picking Elizabeth Bennett, and she might be more fun to hang out with. However, I think Elinor would be a truer friend and would give better advice. I get the impression that she doesn't make friends with just anyone, but she holds onto the friends she does make closely.
9.) Alice from the Alice series - I grew up with Alice, and the series is still going although I have surpassed Alice in age. She has all the typical sorts of teenage troubles, but one of the themes that this series stresses the most is friendship. Alice has her ups and downs with Elizabeth and Pamela, her two closest friends, but they have managed for years to stay friends with each other and in tough times that's who Alice turns to. I relate well to both Alice and Elizabeth, so I'd probably enjoy spending time with either of them.
