Harlequin / Mills & Boon

Harlequin / Mills & Boon

As a successful romantic novelist – one of my publishers is Mills & Boon. I create the sort of male heroes that no woman could fail to adore and few real men could hope to emulate.

What is Harlequin / Mills & Boon Romance?

Mills & Boon was founded in 1908 by Gerald Rusgrove Mills and Charles Boon as a general publisher, moving towards romance and romantic fiction in the 1930s.

In the 1950s, Mills & Boon entered into an agreement with Harlequin Enterprises to allow their titles to be published in North America.

In 1971 Mills & Boon was sold to Harlequin Enterprises.

Today, Mills & Boon is a romance imprint of British publisher Harlequin UK Ltd.

Books are sold and marketed as Mills & Boon in the UK and Harlequin in North America.

Both Mills & Boon and Harlequin have a number of different series / lines / imprints – some are the same, some are the same but with different names, and some are completely different! These lines cover a range of different types of stories, settings, heat levels etc.

There are also numerous defunct lines – imprints/series’ that are no longer published or have been retitled or rebranded, but are still available to buy from retailers.

There are far too many lines – past and present – to list them all, so I’ve just concentrated on my favourites and those that I’ve written reviews for.

However, if you fancy having a look at all the lines, have a look at the READ MORE section.
