On the contemporary side, I like MG narratives that have a lot of heart and deal with meaningful topics (think FROM THE DESK OF ZOE WASHINGTON and FRONT DESK). I also love MG stories that deal with all the stomach-swooping and awkwardness of that first crush.
On the fantasy side, I still tend toward contemporary fantasy -- especially because of the potential for goofy MG shenanigans -- however I'm more open to higher fantasy in MG.
Some of my faves: AMARI AND THE NIGHT BROTHERS; GHOST SQUAD.
I tend toward upper MG, and love fantasy and contemporary narratives, but voice is the most important element for me in this age category. I want funny/quirky/snarky MG voices, something really strong that hooks you in immediately.
Here it is! The #MSWL thread!
The broadest strokes are that I'm looking for Adult romance; YA romcoms, contemporary, and the odd spec fic; and MG contemporary and fantasy. Specifics below.
