Kerstin Wolf has just opened up her books again so I've just queried her.
Right now she's only looking for MG and YA manuscripts, so if that's you, get over to her site now!
It's all done online and she wants your query and first 10 pages of your manuscript. She seems to be open for illustrators too but that's just from looking at the site, rather than anything she's asked for.
Go get 'er! 😃
