What Are The Longest-Running Top Romance Novel Series?

When it comes to romance novels, there are a few publishers that consistently stand out. Harlequin is a giant in the industry, known for its vast array of romance subgenres, from contemporary to historical. They’ve been around for decades and have a loyal following. Avon is another big name, especially for historical romance fans, with authors like Julia Quinn and Lisa Kleypas under their banner. Berkley, an imprint of Penguin Random House, is also a favorite, publishing popular titles like 'The Kiss Quotient' by Helen Hoang. St. Martin’s Press is another key player, offering a mix of romance and women’s fiction. These publishers have shaped the romance genre and continue to bring us some of the most beloved stories.

The 1980s were a golden era for romance novels, and several publishers dominated the scene with their iconic titles and series. Harlequin was undoubtedly the king of romance during this decade, with their category romances like 'Harlequin Presents' and 'Harlequin American Romance' selling millions of copies worldwide. Their books were everywhere, from grocery stores to airports, and they set the standard for the genre. Another major player was Silhouette Books, which launched in 1980 as a direct competitor to Harlequin. Silhouette quickly gained a loyal following with their 'Silhouette Special Edition' and 'Silhouette Desire' lines, offering slightly more contemporary and diverse stories. Dell Publishing also made waves with their Candlelight Ecstasy line, which pushed boundaries with steamier content, appealing to readers craving more passion in their romances. Bantam Books and Avon were also key publishers, releasing standalone historical romances that became instant classics. Authors like Jude Deveraux and Johanna Lindsey found huge success under these imprints. The 1980s romance market was vibrant and competitive, with each publisher carving out their niche, whether it was sweet, spicy, or somewhere in between.

Romance fiction has some powerhouse publishers that dominate the scene, and I’ve been following them for years. Harlequin is the undisputed king of romance, churning out everything from sweet small-town love stories to steamy international affairs. They’ve been around forever and have a knack for knowing exactly what readers want. Then there’s Avon, which is part of HarperCollins. They’re known for their historical romances and contemporary hits, often with strong, sassy heroines. Berkley, another big name under Penguin Random House, focuses on romance with a bit of everything—paranormal, suspense, and even cozy rom-coms. St. Martin’s Press is another heavy hitter, especially with their Griffin imprint, which has published some of the most iconic romance novels of the last decade. They’re great at blending romance with other genres, like mystery or fantasy. And let’s not forget Entangled Publishing, which has made a name for itself with its diverse and inclusive stories. They’re smaller but punch way above their weight, especially in the indie romance scene. Finally, there’s Sourcebooks Casablanca, which has a reputation for heartwarming and emotional reads. They’ve been gaining traction lately with their focus on both contemporary and historical romance. These publishers are the backbone of the romance genre, and their catalogs are a treasure trove for anyone who loves a good love story.

As someone who spends way too much time browsing bookstores and online shops for fantasy and romance novels, I’ve noticed a few publishers consistently delivering top-tier content. Tor Books is a powerhouse in fantasy, responsible for gems like 'The Wheel of Time' series and 'The Name of the Wind.' They have a knack for picking up epic, world-building stories. On the romance side, Avon Books is legendary, publishing classics like Julia Quinn’s 'Bridgerton' series and newer hits like 'The Hating Game.' Penguin Random House also dominates both genres, with imprints like Berkley (romance) and Del Rey (fantasy). Berkley gave us 'Outlander,' while Del Rey is home to 'Game of Thrones.' For indie vibes, Orbit Books is fantastic for fantasy lovers, with series like 'The Dresden Files.' And let’s not forget Harlequin, the romance giant behind countless swoon-worthy reads. These publishers have shaped my reading journey, and their catalogs are a treasure trove for fans.

I've been diving deep into mafia romance lately, and a few authors have completely stolen my heart with their gripping, dark, and passionate storytelling. Penelope Sky is an absolute queen of the genre—her 'Banker' series is addictive, blending ruthless mafia dynamics with intense emotional stakes. Cora Reilly’s 'Bound by Honor' is another masterpiece, crafting a world where loyalty and love clash in the most tantalizing ways. Then there’s J.T. Geissinger, who adds a unique twist to mafia romance with books like 'Beautifully Cruel,' where wit and danger go hand in hand. Danielle Lori’s 'The Made Men' series, especially 'The Sweetest Oblivion,' is a must-read for its sizzling chemistry and complex characters. Lastly, Kresley Cole’s 'The Professional' stands out for its blend of raw power and seduction. These authors have a knack for making you root for morally gray characters while keeping you on the edge of your seat.

I’ve always been drawn to Christian romance novels because they blend faith and love in such a heartwarming way. In 2023, one standout for me was 'The Love Letter' by Rachel Hauck. It’s a dual-timeline story that weaves together past and present, with a strong message about forgiveness and second chances. Another favorite is 'True to You' by Becky Wade, which has this perfect mix of humor, romance, and spiritual depth. The characters feel so real, and their struggles with faith and love are relatable. I also enjoyed 'The Secret Life of Sarah Hollenbeck' by Bethany Turner—it’s funny, heartfelt, and tackles some deeper questions about identity and grace. These books aren’t just about romance; they’re about growing closer to God while finding love, which makes them so special.

I've been diving deep into the world of romance werewolf novels recently, and I’ve noticed a few publishers consistently putting out fantastic reads. Harlequin’s Nocturne line used to be a powerhouse for paranormal romance, including werewolf stories, before it was discontinued. Now, I find myself gravitating towards indie publishers like Entangled Publishing, especially their 'Embraced' imprint, which has some steamy werewolf romances. Samhain Publishing was another favorite before they closed, but their legacy lives on in digital formats. For self-published gems, I often check out authors on Amazon Kindle Direct Publishing—some of the best werewolf romances I’ve read came from there. The indie scene is thriving, and it’s where I find the most unique takes on the genre.

As someone who devours bodyguard romance novels like candy, I've noticed that certain publishers consistently deliver high-quality stories in this genre. Harlequin's 'Romantic Suspense' line is a powerhouse, offering steamy, action-packed tales like 'The Bodyguard' by Katherine Center. Entangled Publishing also stands out with their 'Brazen' and 'Ignite' imprints, featuring titles such as 'Protecting What\'s His' by Tessa Bailey. Carina Press, an imprint of Harlequin, specializes in digital-first romance, including bodyguard tropes with a modern twist. Then there's Berkley, known for blending romance and suspense seamlessly, as seen in 'The Witness' by Nora Roberts. For indie lovers, self-published authors like Anna Hackett dominate the Kindle Unlimited charts with series like 'Team 52'. Each of these publishers brings something unique to the table, whether it's gritty realism or over-the-top alpha heroes.
