Fantasy Romance
Format: Kindle
✨’Would it truly be that bad?' he muttered, and for the first time since she'd awoken, there was a hint of humanity in his quiet words, a crack in that jaundiced shield. Warm breath brushed past her scalp. His arms didn't let go. 'If you ended up here with no way to leave?' ⭐️⭐️⭐️⭐️⭐️ 🌶️🌶️🌶️ Fantasy Romance 📖 🥀Oh, these moment with our MMC reach deep for me and make me love him all the more! Curse Of The Thorn King is @authorlisettemarshall’s new and utterly enchanting Beauty and the Beast retelling, and I absolutely loved it! This steamy, forced proximity, enemies to lovers story is the first installment in the new Wayfarer Fae series and I fell hard for these characters! ✨I thoroughly enjoyed the unique flower magic systems, the assassin plot, all of fun additions of Lady Lockwell's Handbook of Etiquette, and how that factored into the story. The flirtatious and stabby banter between the two main characters had me grinning like a complete fool as the romance developed….all while experiencing the moments that made my heart ache and even break for our MC’s as the plot unfolded. 🥀As I read Curse of the Thorn King I was consumed by that quintessential balance of angst, tension, steam, COMPLETE frustration (in the best way) emotional turmoil, and swoon worthy moments that my heart has come to associate with the magic of Lisette Marshall’s writing. This authors always makes me feel allll the feels ✨✨It is no surprise that I intimately drawn to these characters and their story. ✨I highly recommend Curse Of The Thorn King to fantasy, fantasy romance, and romantasy readers.

5 ⭐️ / 2.5-3 🌶️
Format: Paperback
I do not know where my original review went so I’m reposting Includes: - Beauty and the Beast vibes, but with a Fae twist - Enemies to lovers - Slow burn - Forced proximity - Standalone HEA There are now two books I love that have opening sentences that reference bars of soap. @authorlisettemarshall ‘s books never disappoint me and this standalone is no exception. I absolutely love her writing style, the unique magic systems she uses, as well as her ability to convey such vivid details regarding things like clothing and places. It really helps someone like me (who isn't a good visualizer) immerse myself in the story. It also MUST be said that Lisette has really mastered the art of writing the slow burn for me. With fun characters and banter, she sprinkles in little breadcrumbs here and there that help with the romance build up and, baby, I'm hot on those breadcrumbs' trails just EATING them up. TLDR; Put this on your TBR.

Fun and steamy read
Format: Kindle
Fun read with some of my favorite things: enemy to lover trope, magic, badass FMC, some build-up/steam, and the occasional glimpse into the MMC’s POV.

so good
Format: Kindle
I’ve read any number of fairy tale retellings and I believe this one is top ten. The characters are likeable but complex enough to be interesting; the plot stands alone but leads you to the next book. The dialogue is also quite clever.

Nice standalone
Format: Kindle
3.5 stars. Reminds me of the old school romances of the 80s and 90s. Boy meets girl. They fight. They fall in love. Boy screws up. Girl flees. They kiss and make up. One thing that I absolutely adore about Loretta Marshall's worlds is just how inventive she is with the magic. Magic via flowers? How does her brain think of these things?
