One of the things that strikes me as I listen to these books (I'm a huge audiobook fan) is how well Mead handles the unique and often quirky personality differences between Sydney and Adrian. And I'm not just talking about the fun voice differences the reader provides.
Adrian is a recovering playboy. Kind of. lol He's funny and he's flirty and he's self-denigrating. Adrian's flawed and still finding his way as he grows up and learns to deal with his magic (which could eventually drive him insane--literally). Here are some examples of the kind of quips he comes up with:
“I know how devastated you must be to miss me, but leave a message, and I'll try to ease your agony.”
“Who is he?"
"An idiot," said Adrian. "Makes me look like an upstanding member of society.”
“You look confused," said Adrian.The books are written in first person--from Sydney's point of view--so we don't get into Adrian's head. His comments do a great job of showing the reader what frame of mind he's in at the moment.
I shook my head and sighed. "I think I'm just overthinking things."
He nodded solemnly. "That's why I try to never do it.”
Mead has more flexibility with Sydney because of the first person writing, but I think this is where the author excels. The things that Sydney notices and thinks about are so "Sydney." She's brilliant, analytical, and totally a novice when it comes to feelings. Even her battle scene descriptions reflect how she views the world. She's a rule keeper and even her internal thoughts reflect that--if she's trying to break into someone's apartment and the ratty fire escape looks like it needs repair, she'll wonder why someone didn't report it, all while she's hanging two or three floors above the ground.
This is what we need to do with our characters. Make sure that we're capturing the uniqueness that is each one. Do you have any tips for doing that?
