Please read the information on this page carefully.

These pages are designed to be a guide, not a substitute for extensive reading and research. There is no formula for writing a publishable romance.

The editors for each of the series have simply written guidelines that reflect their series' requirements. As a result, each set of guidelines “reads” differently, with some more specific than others, depending on the degree of focus the editors would like their submissions to have.

What are some other things you can do to help sell your manuscript?

First, we expect you to enjoy reading romance fiction. If you are already a fan, your appreciation for this type of book will be apparent in your writing. If you have not done so already, we encourage you to read many, many books from each series. The series that emerges as your favourite is probably the one to which you should submit your manuscript.

Second, remember reading is an emotional experience. We hope you will write from the heart and we will feel touched by what you have to say. When you put pen to paper (or finger to keyboard), do so because you have something to share with other readers.

You will also find answers to some frequently asked questions. Should you require further information don't hesitate to contact the appropriate Editorial house. Good luck!

Many writers ask similar questions while preparing their romance-novel manuscripts for submission. Here are a few of the most popular questions with answers from our editorial staff.

How do I know which series to write for?
By reading books in each series you'll find a series that you like best. This is the series that you should write for.

Do you really read every submission?
Yes. Because of the large number of submissions we receive, however, our response time to each submission varies.

Do I need an agent?
Harlequin Enterprises/Mills & Boon works with both authors who are and authors who are not represented by agents.

How do I know if my manuscript has been received?

You must be registered with Submittable to submit your manuscript. You will be prompted to create an account when you begin the submission process. Please submit to only one category at a time, with only one submission at a time.We accept submissions in English only.

What are the most common mistakes an author makes when she sends in her manuscript?

Authors often forget to state which series or which editor the manuscript is meant for. In some cases an editor is in charge of more than one series. Therefore, it is very important to state this information clearly in the cover letter or on the front of the manuscript.
