When it comes to romance releases, June 2025 was busting out all over!
From Meghan Quinn’s best friend’s brother love story to Ali Hazelwood’s first age gap romance, it’s clear that readers were all about the tropes in June.
As romance aficionados, here at Swooon we’re always dying to know what love stories other readers are devouring. That’s why we team up with indie bookstores across the US and Canada every month to find their best-selling romance novels. Now that we’ve hit 2025’s halfway point, we’re excited to look back at the bestselling novels from June. Continuing a trend of four out of five new entries to our ranking, this month saw three authors break into the top five (one entered our top five with two books!), and one author who held onto a top five spot.

A Kingdom of Stars and Shadows
Holly Renee
As the first book in Holly Renee’s self-published Stars and Shadows series, A Kingdom of Stars and Shadows has had many avid fans since 2022. However, June saw a Stars and Shadows renaissance like no other, due to the republication of the series through the trade publisher Sourcebooks. A Kingdom of Stars and Shadows follows a steamy love triangle between Adara, the fae prince she is betrothed to, and the half-fae at his side. If you’re into men who could be described as a “possessive shadow daddy,” this is certainly the romantasy for you.
Till Summer Do Us Part
Meghan Quinn
Fans of The Unhoneymooners, Till Summer Do Us Part is the sizzling summer fake-dating romance for you. Finding herself working in a male-dominated company, Scottie Price lies about having a husband in order to impress her new boss. As her fictional love story spirals out of control, Scottie finds herself at an eight-day summer marriage camp with all of her coworkers and her best friend’s brother, who is posing as her husband. Warning: If you’ve ever been scarred by a college improv-troupe performance, do NOT pick up this hilarious romance.
Lights Out
Navessa Allen
The first of two Navessa Allen books on our June Best Sellers list, Lights Out is the dark romance to end all dark romances. To some, a masked stalker breaking into their house would be an absolute nightmare. To Aly, it’s the height of romance. As things heat up between Aly and her morally gray lover, Josh, she catches the attention of a far less sexy threat. If you like your romance with a heaping side of content warnings, be sure to check out this spicy (albeit disturbing) love story.
Problematic Summer Romance
Ali Hazelwood
Ali Hazelwood is no stranger to a beloved trope, so it’s no surprise that she has finally dropped an age gap romance. For the second consecutive month, Hazelwood’s Problematic Summer Romance has made our top five list. Taking readers on a Sicilian vacation, Problematic Summer Romance follows a 23-year-old woman with a massive crush on her brother’s 38-year-old best friend. While wedding bells ring for her brother, Maya embarks on her own unconventional love story.
Caught Up: Into Darkness Trilogy
Navessa Allen
Following in Lights Out‘s footsteps, Navessa Allen’s second Into Darkness book, Caught Up, is a dark romance with a second-chance romance twist. The story follows Junior, a mafia heir, who fell in love with a bookish girl from afar in high school. Now that he’s grown up, he has learned (with the help of some light cyberstalking) that his crush Lauren is no longer the shy girl he once knew. Readers, be warned, if you thought the content warnings for Lights Out were extreme, you clearly haven’t picked up its steamy sequel.
