Callie Hart is used to doing things her own way, so when it came to the paperback release of Quicksilver and Brimstone, she had something new up her sleeve. This time she is working with Patreon to give her biggest fans a closer look at what is coming up next in her world.
Cosmopolitan can officially reveal that Callie Hart will be expanding her current Patreon page to include new fan membership options that span from $1, $5, $15, $25, and a top tier at $70 per month. According to the author and the service, fans can expect some brand-new behind-the-scenes moments like:
- Sneak peeks and word-count updates on in-progress novels.
- Early access to her character art, events, and pre-order links.
- Episodes of a new ‘In Conversation With…’ interview series where Callie sits down with other best-selling authors.
- Signed and personalized bookplates, art cards, and personalized first editions of new releases for members of the highest tier.
“Romantasy novels have built one of the most passionate fandoms. Readers aren't just finishing a book, they're discussing theories, sharing character art, and seeking a direct line with the authors behind their favorite stories,” said Leticia Hirabayashi, Head of Creator Acquisition at Patreon. “Callie Hart has built one of the most devoted communities in the genre, and Patreon gives her a space to bring fans even closer through exclusive sneak peeks and behind-the-scenes moments between books that make her universe feel shared, not just consumed.”
One of the first major reveals? The paperback special edition covers of Quicksilver and Brimstone!
“We always knew the paperbacks were going to have exclusive new character artwork, and I’m so thrilled that we can share these editions at last,” Callie exclusively told Cosmopolitan. “I’m horrible at keeping secrets, so being able to share these new special editions now is amazing. I hope the readers love them as much as I do.”
Fans who subscribe starting now will get the chance to check them out as soon as they sign up. Looking for a major sneak peek?

“I’m so excited for the new paperback editions of these books. For Quicksilver, this artwork is a real nod to the original cover, and I love that. With Brimstone, Saeris finally has her moment to shine.” Callie continued. “The new art has really captured how badass she is, and I’m over the moon that Onyx has made an appearance, too.”
