My Services

I’m a seasoned children’s book editor and award-winning author. I have experience editing picture books graphic novels, middle grade novels, and non-fiction YA titles with many publishers, including Annick Press, Kids Can Press, Owlkids Books and Tundra Books. I’ve worked with diverse creators, from emerging writers to experienced children’s authors. I’m passionate about on a wide range of fiction and non-fiction projects of different genres and formats.

Children’s Book Consultation

Do you have an idea for a children’s book but aren’t sure where to begin? Or have you waded into writing but worry that you’ve lost your way? I can help. I offer 30 minute and one-hour consultations for new and experienced writers. I’ll review your query, synopsis, pitch, outline or manuscript (up to 2500 words).  Then, let’s chat!

Editorial Assessment

Looking for some guidance on a work in progress? I’ll provide thoughtful feedback on your manuscript, focusing on structure, characterization, plot, age appropriateness, genre, format and style. Once I’ve had chance to evaluate your draft (up to 2500 words), synopsis or outline, we’ll schedule a phone or video call to discuss your goals and the challenges you’re facing with the draft. After our discussion, I’ll provide a written report and if appropriate comments and line edits on the manuscript to guide you in your revisions.
