I feel like each categorization has its own strengths. YA's is character development and voice. I love vicariously living through someone else, seeing the world through another perspective, having experiences that I've never had. So when I get to hear a strong voice and live through a dynamic and changing character, I feel like I'm getting an electric charge.

This One Summer by Mariko and Jillian Tamaki, which I am really enjoying.
I pleasure-read at home in big bursts. I will finish around 5 books in 5 days, all in paper -- no electronic. Then will get back to my work-reading: student work, research for my next novel, which I do electronically. So, I read for that anywhere I can bring my computer. Right now, for instance, I'm reading student work while I'm waiting for my daughter in the dentist's office.

Recommendations are generally what draw me to a book now. I understand that covers are marketing choices, not authorial choices and so I pay little to no attention to them. Similarly, the blurbs often give away too much. But I have a group of writer friends whose recommendations I always take. HM Bouwman, for instance, has turned me on to so many good books, including one of my favorites of all time: Code Name Verity. So now, I'll read anything she hands me.
Oh I reread all the time. I'd say more than half my reading is re-reading because when I find a book I love, I want to study it as an author. And, before I teach anything, I re-read it. So I've re-read, say, Code Name Verity three times last year. This year, I suspect I'll be re-reading We Were Liars at least two times.
Probably SPEAK by Laurie Halse Anderson. I learned you could speak directly to kids authentically and not in a sort of Saturday Afternoon Special style. SPEAK got me reading YA as an adult and from that book, I realized I wanted to write YA.
Which books do you find yourself recommending over and over again?
So many! But I'll limit myself to 5 YA titles that I haven't mentioned already.
