Fallen for the Fallen Angel – A Guilty Pleasure Worth Every Page
Format: Kindle
There’s something deeply irresistible about a dark academia or trial-based setting, a brooding and arrogant fallen angel, and a fierce heroine with enough sass to go toe-to-toe with him. Wings So Wicked is exactly that kind of book—and I devoured it in just a couple of days. To be fair, the plot isn’t groundbreaking. If you’re looking for something fresh and innovative in terms of storyline, this might not be it. But if your reader heart beats faster at the mere mention of enemies-to-lovers, jealousy-fueled banter, magical trials, betrayals, and forbidden tension—you’ll feel right at home. It’s like catnip for those of us with this particular weakness. The chemistry between the leads could have used a slightly slower burn to make the tension sizzle longer, but I still found myself completely invested in their dynamic. There are moments and phrases that feel a bit cheesy or underdeveloped, but honestly? I didn’t care. The vibes were exactly what I wanted. This book isn’t trying to reinvent the genre—it’s here to give readers like me what we crave: high-stakes magical drama, angsty romance, and the thrill of watching a badass girl and her brooding counterpart clash and spark. If that sounds like your kind of story, Wings So Wicked will hit the mark. Here’s hoping Book 2 turns up the heat and keeps the magic alive.

Fast paced romantasy you will not want to put down!
Format: Kindle
4.25 stars! I LOVED this book with similar vibes to Hush Hush, Fourth Wing, and The Serpent and the Wings of Night! It was fast paced with easy world building and will keep you turning the pages late into the night because you will not want to put it down! Huntyr is a fierce bad@ss FMC trained to kill vampyres her entire life. She is sent on a mission to go to the academy and earn her spot into The Golden City. Upon arrival, she is forced to room with the delicious fallen angel, Wolf, who is the only one who knows about her assassin identity. The romance, the plot twists, the secrets revealed, the battles, and the tantalizing training scenes had me hooked! And that ending…. I’m holding my breath in need to know hell! Read if you love: 🪽 Fae, Vampyres, Fallen Angels 🪽 Academy setting with magical trials 🪽 Forced proximity and slow burn 🪽 Rivals to lovers 🪽 Hidden identities and secrets 🪽 Tend your wounds “𝘖𝘧 𝘤𝘰𝘶𝘳𝘴𝘦 𝘐 𝘸𝘢𝘴 𝘸𝘢𝘵𝘤𝘩𝘪𝘯𝘨 𝘺𝘰𝘶.

Excellent Rivals to Lovers!!
Format: Kindle
The tension and banter between Huntyr and Wold was delectable. I absolutely love the fallen angel and all of his flaws. Huntyr is amazing too being a badass FMC with some major trauma. The world building was great and I enjoyed the training aspect of the story. The writing was immersive and was in the story the whole time. The ending had quite a twist that I hadn’t anticipated and made my jaw DROP. Excellent job! I also loved the narration. Laura is one of my fave narrators!

AMAZING debut novel!!!
Format: Kindle
Plot ⭐️⭐️⭐️⭐️ Spice 🌶️🌶️.5 Romance 💘💘💘 Vibes ⭐️⭐️⭐️⭐️⭐️ Dual 1st person POV - Ara (26) & Rogue (39 - but looks mid-20s: they can live hundreds of years so this isn't that large of a gap as it could've been which I heavily appreciate lol) Tropes: enemies to lovers, fae/human wars (deep hatred for each other), shifters (dragons- MMC can only partial shift with wings), one horse, one bed, touch her and d!e, found family, abduction turned to freedom The Last Storm is the debut novel from JD Linton and let me tell you, you guys NEED to read this. The plot was engaging and the editing was was amazing (especially for a debut novel). Our FMC, Ara, is stuck in her gilded cage longing for a life outside of her small town. She uses her books to escape and live vicariously through the pages (honestly, relatable). After her father announces her betrothal to her childhood friend (to whom she has no romantic feelings for), Ara tumbles unknowingly into a desperate plot trying to stop the humans from slaughtering the Fae. As one can expect from an enemies to lovers / kidnapper/captive romance, Ara fights her attraction and lust towards our MMC, Rogue (the King of the Fae), for as long as she can. Upon seeing Ara for the first time, Rogue is instantly aware that she is his fated mate (not a spoiler). Since she is the General's only daughter, he plans to abduct her and use her as leverage to stop the brutality. During Ara's time in Rogue's captivity, their banter and chemistry continue to rise until they finally boil over and come together (quite literally, and many times I may add 😉). Here's what I LOVED: - Rogue continuously seeks advice from his elders and deeply respects their opinions and life experience and tries to implement their recommendations - Rogue makes many mistakes in the beginning but we see him actively work on not repeating them as the book progresses. The level of self-awareness and his ability to change his behavior was impressive - The magic system is intricate and we have only scraped the surface. As the series continues and Ara progresses in her powers, I'm sure we'll get to see more of this. I absolutely LOVE the messaging system that is used in this book. - Ara's struggles are so human and so raw. She is experiencing so much guilt and pain and hurt and getting to see her work through each of these emotions is inspiring. Especially as her and Rogue get closer and she learns she can lean on him as well, that she is not alone. - While this is the start of a series, there is NO cliffhanger! There's a bit of a teaser of something major that is going to happen at the start of the next book, but it's not a cliffhanger in the sense that we aren't sure if someone is going to live or d!e or if they'll be separated. For that, I am very thankful! This book was so much fun that I will definitely be returning to book 2, even if it takes several months (or longer since this is an debut author) to publish! - Lastly, the cover is GORGEOUS! And I love the title! I'll copy a few of my favorite quotes below so you can have a little taste of the author's writing and the world she's cultivated. 😊 Top Highlights from The Last Storm On days like this, when my heart was heavy and my mind clouded, I resorted to books— to escape, to forget, to find freedom where I had none. If I were to marry him, my face would always be turned to the window, searching for more, and if not that, I would be a shell of the person I am now. I stepped back to admire her, thr0bbing at the sight. She was the most beautiful woman I had ever seen. To ever exist. Nothing, no one, had ever deserved to be worshiped more. All men should be made to kneel before her. But she would have to settle for me. The taste of her met my t0ngue as my scent merged with hers, forever branding her. Mine. I l!cked the wound. Hers. Completely and utterly hers. I didn’t claim her in ownership. I claimed her as my one. Devoted myself to one. With that mark, my body and soul were bound to her. I would never be with anyone else, emotionally or physically. It would be her or no one, until my last breath. “Scream my name. Let everyone know who I belong to.” I had never really cared about the weather before, but now, clear skies meant everything to me, and I was grateful to see another calm morning. “There will never be another woman for me.” He paused. “Ever.” I stilled at his words. “What… Why?” “This”— his thumb slid down across the mark—“ is a symbol of… surrender. I know you believe that it was my claim upon you, but it wasn’t. It never was. I bound my body and soul to you, little storm.” “I also know that it is more than this tiny, insignificant mark on your skin that binds me to you. It’s you. All of you. Your strength and resilience. Your determination to endure no matter what fate throws at you. Your love for love and stories and hope. You are entirely the opposite of everything that I am and I would gladly wear your shackles if it meant I could have you.” My mate. Mine. And then everything shifted and I understood. I understood everything. The surrender. The deep, soul-craving longing. Bound. I was bound to him. Body and soul. Entirely his. “I would’ve waited forever,” he whispered back, understanding. Seriously, everyone.. add this to your TBR!!
