Best-seller copy editor Heather Sangster of Strong Finish.

At this level, there’s an art to it.

Hi, I’m Heather Sangster and I’ve been working in the publishing industry since 1988 (as Strong Finish since 2006), honing my technical expertise in multiple mediums, genres, and roles. As a result, I’ve mastered the rules—substantive criteria, style conventions, grammar guidelines—but more importantly I know when and how to bend them (and even break them) to bring out the best in your book. Above all, knowing what works is key—pedantic adherence to a style manual does not an expert make.

Over the years I’ve also become privy to the shifting tastes of literary agents and acquiring editors across the trade genres, and I keep on top of forthcoming trends and new horizons in traditional publishing and self-publishing. Thus, my mission has two goals: to provide ongoing editorial support to publishers and businesses worldwide; and to help emerging writers produce a professional manuscript that will hold an agent’s/publisher’s interest and stay out of the slush pile.

Ensuring that your publishing project is first class all the way, I apply decades of editorial and production expertise earned from long-time service to prominent publishers, authors, and businesses.

I’ve contributed my services to over 1000 books so far, and I’m grateful to have played a role in the achievements my clients have earned: 59 best-sellers, 118 awards, and counting.

Most importantly, I deal in excellence, credibility, and relationships. With respect, patience, and warmth, I’ll collaborate with you to refine your writing because your book matters to you, and it matters to me, and I’ll help make sure that it matters to your audience.
