I will probably say this for all of them but:
Check your triggers! These novellas are dark and the trigger warnings read like a grocery list!

Lucky for me, I'm broken and I like dark! ARC reader and review.

This book is a continuation of book 1 with different characters. Livvy and Hayes and their insta obsession was all I needed. Every depraved part of them. Semi hockey- dark romance. Secret society. Ends on a cliff hanger! Ahhhhh. I'm jumping right into the next.

This one for me was a medium burn before the proverbial sh*t hit the fan, boy did that hit me for six! After how the first book finished one had some hope for the next Valentine. Meh! I may have been punching above the waist there 😂

Once it got going it was an enjoyable read, I loved Liviana all that sass and submissiveness, Hayes the jury is still out on him, time will tell 👌onwards friends….>

This was such a great read! I loved how deranged both Hayes and Liv were, their jealousy and possessiveness were everything, and some people definitely paid the price for it. I’m excited for the rest of this series, but I also need more of Liv and Hayes’ story!

“You’re not supposed to be the one killing for me. That’s supposed to be my job.”
“You wanted me to be yours, so I staked my claim.These bitches better back up, or your friends aren’t going to have pussy to sink their little cocks into because I will slay every last fucking bitch that touches you.” 


Trust me, no one is more shocked by my rating than I am. But it’s been a while since I read about characters as unhinged as these two. They DESERVED a full-length book, not just a novella.

“Please don’t be scared of me,” he whispers, not making eye contact. I move forward and wrap my arms around his waist, squeezing him tightly.

╰•★★ Hayes Valentine ★★•╯

If I could just take all the air from their lungs, fuck their throats just how I want it, and get away with murder, half of the female student body would be dead.

This man was a true asshole, the way he treated, thought about, and talked about women was disgusting, until Liviana showed up, and he went from being just an asshole to being an obsessive, possessive asshole over ONE woman.

“What’s your name?”
“Hayes Valentine.” I stick my hand out but she rolls her eyes. 
“Well, Henry. If you take a second to get your head out of your ass, then maybe you would realize that there are plenty of other seats for you to park your entitled self in. Better yet, maybe you should go sit in your car like you did this morning and lose some more brain cells getting your dick sucked before class.”


You already know the drill, treat them differently from everyone else, and boom, you’ve got their full attention, and she didn’t just get his attention, she got his obsession too.

“I told you to stay the fuck away from her. You took my threat as bullshit and ate her cunt.”
“No-no man, I didn’t do shit. You got the wrong guy.”
“Then why do I smell her sweet cunt on your fucking face?” I growl, pulling his head back farther and bending down to lick the side of his mouth tasting her. “That’s my cunt you ate.”


He was out there killing ANYONE who laid a hand on her, whether it was to please her or hurt her.

“That little stunt you pulled last night will never happen again. If I ever see another man touch you, he’s dead.”

Liviana just had to show up to his game wearing someone else’s hoodie instead of his, and he lost his mind. He fell first and HARDER.

Numb is what I feel and I’m not sure I can hide that from the girl waiting for me. I don’t want to hide it. I want her to know every part of me. The good, the bad and the unhinged. I just pray she can accept me and the killer I am.

╰•★★ Liviana Jericho ★★•╯

“That cock you just had down your fucking throat is mine. This is the third time I’ve seen you gagging on him, and I’ve had about enough of it.”

I really liked her because she could match Hayes' level of madness, just as jealous and possessive as he was. She was Bonnie and he was Clyde literally.

Why did he kill him? Why did I run? Just because his hands were full of blood doesn’t mean I was scared. I was just taken aback by the scene. I’d be a hypocrite to be frightened of him. Fuck. I shouldn’t have left. I could’ve helped him get rid of the body.

What I would've liked, though, is for her actions to be explained better. Like, I remembered when SHE remembered that she had a boyfriend only after messing around with two different guys in less than 24 hours.

“Ask her about Dillon. She has a whole boyfriend back home. My younger brother. If you don’t believe me, ask her. Or better yet, ask her why she’s here.”

I know she’s possessive and hiding things, but beyond that? I don’t really know her, and that’s why I have mixed feelings about her character. I guess all these questions will be answered in the next book.

╰•★★ Hayes and Liviana ★★•╯

“You’re hers but obsessed with me? That's rich.”
“Says the one with a whole boyfriend back home.”
“So instead of having an adult conversation and asking questions, you decide that it’s a good idea to go get your dick sucked after killing someone who hurt me. Make it math Hayes. You’re not stupid. Dumb, yes. But not stupid.”


Oh I loved them, I LOVED THEM.They had potential and they definitely served but, I’ll say it again, they could’ve been so much better if this was a full-length book. I mean, LOOK AT THEM:

I gently wash him, being careful around the fresh wounds. Placing my lips against his back, I kiss every single fucking scar, every slice, every mark.

“Leave your mark, baby. I want everyone to know I’m yours.”

“I promise you now, Liviana, if I ever see another man's hands on you, the killing will never stop. No one gets to touch you, nor hurt you, but me. You got that?”

“I want you to bleed with me. Will you do that for me, baby?”

They were obsessed, possessive and protective with each other, but not only that, they also had these sweet, intimate moments where they took care of each other and were affectionate. Less than 100 pages, and I totally believe they’ve developed feelings for each other. That’s how strong their bond was, but I also have to say, I liked them more as a couple than as individuals.

“Are you fucking kidding me right now?” I shout as he pays no mind that i’m literally yelling while he’s getting his dick sucked.
“Do you mind?”
“Oh, I fucking do mind, Henry.”


Anyway, good novella, LOVED the couple AND the plot, I can't wait for their second book.

“Remember, Sinister Valentine, you made me do this.”

Soooo good! The continuation of the story from bloody valentine was beautiful done. The authors meshed the stories together brilliantly. But that cliffhanger seriously, I have to wait til next winter to know what happens will be my internal death like worse than waiting for any other book out there. Definitely worth a read!

Ashlynn’s Sinister Valentine is a thrilling continuation of the St. Valentine series, diving deeper into the shadowy world of family cult rituals, hidden secrets, and a love that straddles the line between passion and peril. This installment shifts focus to Hayes, the brother of the previous protagonist, who finds himself caught in a web of expectations and dark traditions that have shaped his upbringing.

From the outset, Hayes is portrayed as the quintessential hockey-loving, party-spirited young man who is reluctant to embrace the sinister legacy of his family. His character is relatable and refreshingly grounded, which makes his struggles against the cult's influence all the more compelling.

Enter Liviana, the fierce and enigmatic female lead whose arrival at Valentine School brings a fresh wave of intrigue. The instant connection between Liviana and Hayes is palpable, and Ashlynn masterfully captures the tension between them. Liviana’s own secret adds layers to her character and creates a sense of mystery that keeps readers guessing. The chemistry between Hayes and Liviana is electric, making their interactions both thrilling and emotionally charged.

The plot unfolds at a brisk pace, with Ashlynn expertly weaving together themes of possession, identity, and the consequences of love. As the two protagonists grapple with their feelings for each other, the narrative takes a darker turn, exploring the lengths they are willing to go to protect what they desire.

Ashlynn's writing shines in her ability to balance romance with suspense, creating a gripping atmosphere that is both captivating and chilling. The vivid descriptions and well-crafted dialogue immerse readers in the world of Valentine School and its eerie traditions.

Sinister Valentine is not just a tale of young love; it’s a darkly enchanting exploration of how the past can haunt the present and the ways in which love can both liberate and imprison. Ashlynn has once again crafted a story that is as thought-provoking as it is entertaining, leaving readers eagerly anticipating what comes next in this twisted saga.

Sinister Valentine is the second story in the St. Valentines series and is a continuation of the first story (Bloody Valentine). We got a brief glimpse of Hayes Valentine in the first book, but it really didn't do him justice!

Hayes Valentine is a f*ckboy hockey player who is struggling against his family legacy of cult sacrifices and death. Liviana was sent to St. Valentine's by her parents after "inappropriate behavior" and she immediately butts heads with Hayes. Neither of them can deny their innate chemistry, but they have to face various challenges if they actually want to be together.

I absolutely loved Hayes and Liv. Hayes is struggling to fight the influence of his family's secret society while also maintaining his party-loving hockey persona. Liv is fiesty and defiant with secrets of her own including a boyfriend back home. They match each other's energies amazingly and the spicy scenes were deliciously dark and twisted.

The story of Hayes and Liv will continue in Bleed With Me which is set to be released in winter 2025 and I cannot wait. Definitely pick this one up, but make sure to check the long list of triggers first!

Hayes. Hayes Valentine. How you doin. 😈

Quickly please read your trigger warnings!

This is book two of the St Valentines series and getting a small glimpse of Hayes in book one did him no justice. WOW. I'm blown away! He's a savage, obsessed, unhinged hottie who will get what he wants when he wants it. Both Hayes and Liv sure do match dark energy which makes this novella so HOT! 🥵

I did scream at the end with the unexpected cliffhanger but have no fear the next book is coming soon!

I received this as an ARC for my honest review! I loved this novella!

As the second book in an interconnected novellas series with a fairly strong first book, I had high hopes for this one. When it came to introducing characters who will be the stars of the other novellas and including some intensely spicy scenes I thought it did really well. It wasn't as dark as the first book, but it there was one scene in particular that was disgustingly gory (that's not a bad thing, it served its purpose in the story).


Unfortunately though, I think there was a lot that could have been done differently to make this a stronger story. I would have liked to see the importance of fate be carried over from the first book. Liv and Hayes both feel a pull towards each other, but it's not explored much past that. It would have been nice to include the importance of fate since Hayes is a Valentine as well. There was also one particular death that I was disappointed in (I won't spoil it here) but not because of poor writing or anything, I just would have liked to see this character survive throughout the series longer.

If you’re looking for a gory, horror-filled, spicy Valentine’s Day romance then this is the book for you! Hayes and Liviana take it to the next level with their undeniable connection from the first second they lock eyes. This is a continuation/intertwined story with Bloody Valentine, and although this definitely stands alone you will have a lot more context to the characters if you read it first.

Also, at ~80 pages this book was definitely just a small teaser as it ends on a little bit of a cliffhanger with a callout to a follow up book coming later in 2025!

I enjoyed getting to know two more characters from the St Valentine series. I loved how Liv and Hayes story is an instant attraction with some possessive touch her and die vibes. I wasn’t expecting how it ended and now I can’t wait for the book to come out to get more of Liv’s story!

Another great part to the series! Beautifully wrote by an amazing author! Can’t wait to read the entire book! Hayes and Liviana are more alike than they know. Seeing them in the beginning playing games and ultimately in the end no one can touch the other but themselves or else… definitely one I couldn’t put down!

This is the second book of St. Valentines Series a shared world. The author delivers the promiscuous hockey player, Hayes Valentine; Maddox’s younger brother. She brings out his twisted soul and killer instincts.

The author also brings us a savvy character named Liviana. She also has a devious past and blood lust of her own!

However, when her past resurfaces the author opens doors for more to come!

I will absolutely be ordering BLEED WITH ME from this author!

Read responsibly

Sinister Valentine is book two in the St Valentine series and features Hayes and Liviana. He's the hot shot hockey player whose family runs to school and she's the new girl. There is an instant attraction between them but he's a playboy and she doesn't like jocks. They keep flirting and finally giving in. Their darkness matches each other. Ends on a cliffhanger, setting up for Ashlynn's book coming out soon.

This was a fantastic seamless continuation of where we left off. In this story we learn more about Hayes and his role in all the chaos. Undoubtedly women and their effects they have on these men play a huge part in the story. The events are very much sinister and the anticipation is indescribable.
