When I saw this question I didn't have to think that hard. I'd just finished reading Sonya Sones' WHAT MY GIRLFRIEND DOESN'T KNOW for the upteenth time while on vacation (I'd brought a bunch of new books, was disappointed with them, stopped reading them and reached for Sonya's book because I knew it was guaranteed pleasure).
So I'm fine with admitting that my writerly crush is Sonya Sones. I love her books so much. I wish she could publish them as quickly as I read them (impossible).
What makes them so special? They're written in verse, for one thing. Sounds odd, right, they're poems! But they're not! But they are. Yet Sonya's books are brilliant. Every word counts. How she can convey so much on a single page with maybe 50 words is beyond me. And she manages to make an entire book out of it!
If you haven't read Sonya's books, please do so. Every one of them is perfect. And you will wonder how the heck she manages to do so much with so little.
