Ronan Sadler, M.A.

Toronto, ON M4W 3W9


I'm a developmental and line editor; I offer compassionately critical evaluation and editing of young adult, new adult, romance, memoir, and speculative fiction manuscripts. I'm an acquisitions editor at Carina Press (an imprint of Harlequin) and I have interned with literary agents Sara Crowe and Jenny Bent, where I focused on the Yong Adult market. I'm familiar with the intricacies of the traditional publishing industry, as well as the demands of the independent and self-publishing markets. 

I work with authors at all stages of their careers, but I'm particularly skilled at helping first time authors get their books out into the world. Whether it's a multi-year passion project manuscript or a roughly sketched outline and a dream, I guide authors through the process of bringing their first novel to completion. With established authors, I focus on growing craft and refining voice to help bring an author to the next stage of their career.  

My editing style is highly collaborative and holistic. I strive to be in conversation with the manuscript and the author, to guide and nudge, and to challenge where necessary.  I offer a particular sensitivity to the social context we bring to our writing, and I use that to help authors refine their stories and express their truths.  

I have a Master's degree in Critical Disability Studies and a B.A. (H) in English and Philosophy. My scholarly work was published in the collected volume Disability Studies and the Environmental Humanities (UNP 2017), and I have received grants and scholarships for my research. In addition to fiction and memoir, I also edit academic work in the social sciences and humanities.
