The Mashieverse #2

Poison Princess

He's the only one immune to her deadly touch.

A decade after The Big Mash-Up, Capital City is safer than ever. The villain rehabilitation program is a success!

...So they say.

Recently released from Gnistra Lake Penitentiary, Tabitha Lima—AKA Poison Princess—knows intimately all the flaws Capital City tries to hide. Their government made her who she is, after all.

Gave her poison skin. Made her untouchable. Turned her into a monster.

As an opossum Mashie with a Heroes and Villains kink, Henry can’t believe his luck when he meets *the* Poison Princess—no, Tabitha. She’s the tall, curvy, powerful woman of his dreams.

When they find out he’s the only person immune to her poison touch, he’s determined to find the key to her heart.

But her trust is locked up tight, even if she’s not currently behind bars.

Poison Princess is an adult Superhero Romance with an unrepentant Villain as the lead. There is a summary of the first book in the series at the start of Poison Princess which makes this a standalone story; however, as with all series, it's best if you read Goat Girl as well. The content notes are in the front of the book if you need them and the author is always willing to answer additional questions.

196 pages, Kindle Edition

Henry was an adorable kinky golden retriever who was immediately all in on Tabitha. Tabitha was jaded and grumpy, trying to survive a world that hated her post prison. Luckily she figured out pretty quickly that Henry was the real deal and they were good partners for each other. This wasn’t cozy like Goat Girl. It dealt with serious issues with law enforcement and shady government.

Spice: 3/5

I love morally grey, stand-offish, monstrous women, so of course I've signed up for this ARC. This is a short & spicy paranormal/superhero novella which through the story of Tabitha Lima aka the Poison Princess portrays how people might be made into monsters against their will and how hard is it to get out of the vicious cycle, once you're stuck in the position of being hated, villainized and often unjustly accused because of your reputation.

What I liked:

- Henry being very respectful and adorable, he's a bit clumsy and dorky, but it only made him cuter. He's a bi disaster with an opposum's tail (and some other traits).

- Tabitha is a touch-starved virgin because of her poisonous skin, I liked how the first sex scene portrayed the anxiety and awkwardness of that situation and mixed realistic with sexy in good proportions.

- Dystopian worldbuilding of a city of heroes & villains with abusive police and illegal human experiments showing a mirror to totalitarian governments, but without becoming too bleak or gory about it.

- Tabitha's friends (too often stand-offish fmcs are portrayed as friendless).

- Respectful portrayal of disordered eating.

What I dlisked:

- It was too short, only around 150 pages, which made the relationship feel rushed, the worldbuilding a bit barebones leaving lots to reader's interpretation, and the writing style sparse and lacking description and atmosphere.

CW: illegal human experiments, torture, police brutality and abuse of power, disordered eating, imprisonment, violence & killing, discrimination & biased propaganda. Most of the content is not graphic due to the sparse & brief writing style, so it never gets too gory or disturbing. But if any of these subjects are triggering, take care.

4.5 star rounded up.

I've signed up for the ARC through Sylvia Morrow's instagram open call. I'm leaving my honest opinion as a voluntary review.

‎"I’m not worse for being a monster. I only regret having to live among such fragile beings."
‎— Tabitha.
‎
‎💚 She’s an ex-villain on parole
‎💚 He’s a half opossum with an uncontrollable tail?!
‎💚 First person dual POV
‎💚 He’s a fan (and kinda slutty tbh)
‎💚 Second chance
‎💚 Tail play
‎💚 She saved him
‎
‎When someone grows up fatherless, loses almost everything, including their mother, then gets kidnapped by the government and used as a lab rat, does that really make them evil for joining a villain to get revenge on the people who wronged them?
‎
‎You might want to get to know Tabitha Lima before answering that.
‎
‎Enter Tabitha, ten years after serving her sentence, now trying to live a life as normal as possible with her poisonous skin that makes her unable to touch anyone. Ever. She works at a pharmacy, where she meets our MMC, Henry, who’s half opossum and somehow immune to her?? 😏
‎
‎Yep. That’s basically the perfect recipe for a delicious ✨ workplace romance ✨
‎
‎From the very first chapter, I knew I was going to love Tabitha. Her narration is sharp and sarcastic, and the way she mocks herself had me chuckling right away. She isn’t raging at the world, she’s just tired. Okie, maybe a little angry 😬 But she had every right to be! Also, she has green skin. GREEN. That’s literally my favorite soccer team’s color. Not saying I want it for me, but listen, I support her 💚🥰
‎
‎I love how her quirks aren’t shoved down our throats. Morrow writes Tabitha’s eating disorder and possible OCD (?) in a way that feels natural and organic. It never feels like, "Look! My FMC is quirky!" It just flows with the story and makes sense for her character.
‎
‎And then we have Henry, my new book boyfriend.
‎
‎After reading Goat Girl and then this, I’m convinced Morrow has a thing for cinnamon roll guys, and she’s really good at writing them. But compared to Liam, Henry feels waaaaayy more developed.
‎
‎You can really see the author’s growth from her earlier book to this one. Liam was nice, sure, but Henry is so much more. He’s funny, confident about what he wants, shamelessly down bad for Tabitha, and overall I don’t blame anyone who wants to kidnap him because same 🙂 I wouldn’t call this instalove like the previous book. Sure, Henry starts pining fast, but come on, he basically meets his idol. Who wouldn’t? And don’t even get me started on the TAIL. Why write a book about half human and half animal without tail play?? It’s .... Yummy 😋
‎
‎Even when it accidentally smacks Tabitha in the face once 😂
‎
‎Technically, this works as a standalone, since there’s a quick summary at the beginning, but I highly recommend starting with Goat Girl for better Mashieverse context. It’s short and sweet anyway! And I appreciate hearing the update about Jill and all! I wish we had a cameo tho.
‎
‎Since it’s a bit longer than Goat Girl, Poison Princess has even more to offer. The romance feels smooth, with small misunderstandings that get resolved quickly and just enough tension to keep things interesting. There’s even a cute double date that hints at the next couple in the series. And the spicy scenes? 🥵🥵
‎
‎Normally, I don’t like the touch starved + virgin FMC combo. I mean eeeeww 🤢 That’s usually one of my biggest deal breakers. But here, it makes perfect sense. Of course Tabitha is touch starved and inexperienced. No one has touched her without gloves or cruelty her whole life 🥺 And Henry being so gentle melted me??? 10/10. No notes. I want him and his chaotic tail, even with his ... Very opossum like traits (I was absolutely dying laughing at that scene, you'll know 😭). This book shows how to handle those tropes properly. The only thing that could’ve made it even better is having a pegging scene 💀
‎
‎Seriously, I loved Poison Princess. I was a tiny bit salty that the ARC came only four days before release, like ma’am, give us time to breathe 😡 BUT I ended up devoured it in three days, which is honestly really great for me as a slow reader. Books like this can show up in my inbox anytime and I will not complain.
‎
‎My only real complaint is if the author ever stops the Mashieverse here. Absolutely not ⚠️ Illegal behavior ⚠️ We still have other couples who deserve their stories. I need Jimmy Jam. I need Angela and Mark. Don’t you dare stop writing, Sylvia Morrow. Ka-bam 😉

ARC review
4.5/5 stars
🌶️🌶️🌶️

Thanks so much to Sylvia for the gifted copy! This is my honest review.

I was so excited for this follow up to Goat Girl, and I’m happy to say that this novella really delivered. Not only do we get another fantastic love story set in an alternate version of our reality where heroes and villains are real, we dive further into the lore of what created these archetypal characters in the first place, from their powers to their motivations and personalities.

Tabitha is the titular poison princess - a former villain whose powers come from being scientifically altered with the DNA of a dart frog. Oddly, this is the 2nd story I’ve read this month where the FMC is lethal because of a poison her body creates, and both characters are touch starved and live in fear of the unintentional harm that they cause merely by existing. Tabitha’s fear goes so much further though, and that’s a direct result of her past treatment and the abuse she’s suffered. It presents as extreme self-imposed isolation, and in all the rules she surrounds herself with (dietary, clothing and cleaning).

Henry is our FMC. He’s a mashie, part human spliced with opossum, and a former teacher who now lives on the edges of society. This world isn’t always kind to those who are different and his tail and other opossum features mark him. He works in a stockroom and has a strong fetish for heroes and villains. When Tabitha starts working in the stockroom with him, he practically vibrates with excitement.

This is also like the 13th book I’ve read this year with possums/opossums and I’m gleeful about it.

It turns out that Henry’s opossum nature grants him immunity to Tabitha’s poison. This opens up a world to her that she never dreamed was possible, but it also creates a wealth of fears. What happens when the people who created her - and the people she raged against in her villain days - discover his immunity? What will they do to her and to Henry?

This story is fast paced but it is PACKED with so much emotional growth for Tabitha. But it’s also packed with humor in her relationships with Henry and her former villain comrades. Knowing where they’ve come from and where they are now, this is a girl gang that I would eagerly sign up to join!

Also, Henry pegs himself with his own tail while also railing Tabitha. And it is glorious.

Goat Girl is one of Sylvia Morrow’s books that has had the biggest impact on me. Through the story of a young woman whose DNA is mixed with that of a goat, it denounces the discrimination anyone who doesn’t fit the mold can face. Naturally, I eagerly awaited the next installment in ‘The Mashieverse’ series.

One of my first thoughts while reading Poison Princess was that reality had overtaken fiction. While there certainly hasn’t been a Big Mash-Up in our world, inequality and injustice have continued to grow, and some governments have stopped pretending to be democracies.

To get back to the book, I felt a strong affinity for Tabitha. It’s often said that we’re not born evil, but life can make us that way. In Tabitha’s case, that’s exactly what happened. Although she is perceived as a villain, even while in rehabilitation, as we get to know her throughout the book, we realize that she is, above all, a young woman whose life has been stolen from her. We understand the immense anger she feels, without excusing her actions (although…). It’s hard to imagine how it would be to live a life different from hers when you know that merely touching her skin could lead to someone’s death.

Fortunately, after all the bad things that have happened to us, fate sometimes reaches out to us in the form of a young man whose DNA was mixed with that of an opossum during the Big Mash-Up. A young man full of joie de vivre and kindness, though he’s far from a saint when it comes to his private life 😏 This is how we discover Henry’s contagious good humor, which even Tabitha’s darkness cannot resist.

I don’t think I need to specify this, but I will anyway to be clear: I loved reading Poison Princess, a book in which the secondary characters are just as interesting and important as the main characters.

In this second book of ‘The Mashieverse’ series, Sylvia Morrow continues to refine her talent, turning a rough gem into a veritable piece of jewelry.

I recommend Poison Princess and ‘The Mashieverse’ series in general. I can’t wait to get my hands on a third book one day.

Many thanks to Sylvia Morrow for giving me the opportunity to read an ARC of Poison Princess. This review is my own. All opinions expressed are mine.

Tabitha is such a compelling protagonist. She’s been mistreated, imprisoned, experimented on, and isolated for most of her life, and it shows in the way she moves through the world—guarded, sharp-edged, but sweet underneath it all. Honestly, she won me over early just by apologising to a pillow after kicking it. One, this is absolutely me. And two… you never know if there’s a phoenix feather in there 🥰
Henry is clumsy, feral, genuinely funny, and adorable! Their dynamic is a huge part of why this story works so well—funny, tender, and emotionally gripping. When the stakes rise, they rise HARD, and the payoff is incredibly satisfying!
One line in particular absolutely cemented Tabitha for me: “I’ll be the Villain they think I am.”
YES, TABITHA! 👏
The worldbuilding feels vivid and lived-in, with real stakes and consequences, and it gave me strong Watchmen / The Boys vibes in the best way—messy, complex, dangerous, and immersive without ever feeling overexplained.
I always love stepping into Sylvia’s worlds—they welcome you in with big, cosy arms and just the right amount of feral spice. Her books are always a treat, and I genuinely look forward to every release.

I LOVED the first book and ended it thinking Jill/Liam would be my faves 5ever, they were just SO dang wholesome and sweet and they're the couple you want to live next door to you so you can call to help you find your lost dog or to borrow a cup of flour......

BUT ENTERS POISON PRINCESS (Tabitha, Tabby) and I FELL TO MY KNEES. I loveeeee a strong willed, tormented past baddie. Once again is it because I see myself in her? or want to be her? be on her? all of it? Yes. Once again Sylvia comes in with these unique characters who just pull you right into their atmosphere. WDYM Poison Princess is basically a poison dart frog?! AMAZING, GIVE ME 10 MORE. Tabitha was so angry at the world (rightfully so) and literally is trying to be as rehabbed as she can be. I enjoyed how she never lied and admitted when people deserved what they got, cause dang right they did. My heart broke when you learn the layers of trauma she had to experience, but it does help you understand why she is the way she is. Also I related so much to her anxieties/obsessions surrounding her food. I really appreciate anytime authors write these rituals/obsessions/habits (relating to anxiety/OCD/trauma) and don't play it off as someone just being picky or unable to move on. Sometimes we find safety where we can.

Now whomst would love nothing more than Tabitha to step on them in her villain attire? Henry. HENRY IS A SIMP (yes I'm sorry I have to use this word) who is also a mashed up with a possum!!!!!! BUT WAIT THERE IS MORE!!! HE IS QUEER!!!!!!! SOUND THE ALARMS!!!!!! He also never wanted Tabitha to change or pretend to be who she's not. He loves every single bit of her just the way she is including the green bits, heh. Which again! HOW FUN. I LOVE fun smut.

I can't wait for what else we get to dive into the Mashieverse with next and am manifesting some specific pairings for my own personal enjoyment (Sylvia, I will try my hardest not to run into your DM's). This is also another author who has jumped right on up to one of my top faves. And I'm not even saying this because we are mutuals on social media (but also what a LOVELY added bonus?!) BUT READ THESE BOOKS THANKU!

The second installment in the Mashies universe was even better than the first! It seamlessly continued the interwoven story started in Goat Girl. We also got to hear updates on their story, though from a distance.

Tabitha aka Poison Princess has graduated from the villian rehabilitation program and has been trying to turn over a new leaf. Too bad that leaf seems to be glued to the ground. Though through some many happen stances, she finds someone that is more than willing to help her in anyway she needs...

Henry's life got turned upside down with the mash-up but really has no complaints...Besides his tail seeming to have a mind of it's own. His boring everyday gets turned around when his favorite villain shows up at his work...

Henry is EVERYTHING. I loved his resilience and love of life. His humor was just what Tabitha needed to get out of her own head. She has gone through so many things and has learned to trust pretty much no one. But Henry breaks down those walls bit by bit and it's so cute. Also, hot damn they are smoking together! Like I'm used to tail play but I found out something new with this one 😏

There are so many directions this universe can go in and I cannot wait to see what comes next. Because some big things happened at the end of this book.....

Thank you to the author for a copy of this book.

I didn't think it was possible to love this book more than Goat Girl, but I just might! Tabitha is sharp, angry, exhausted, and completely justified. The system made her into Poison Princess and then expected gratitude for “rehabilitating” her. Watching her move through the world—untouchable, guarded, still simmering—felt raw and true.

And then there’s Henry. A half-opossum, tail-wielding, shamelessly down-bad cinnamon roll who meets his villain crush at work and just… goes for it. The fact that he’s immune to her poison touch starts to break down the walls she's built. She’s been denied safe contact her entire life. He wants to hold her. That shift wrecked me a little.

Their dynamic is funny, tender, and very hot (the tail earns its page time). I also appreciated that Tabitha’s trauma isn’t erased by romance. She’s still complicated. Still prickly. Still deciding who she wants to be. And Henry doesn’t try to fix her, he just stands beside her to help however he can.

I’m fully invested in wherever the Mashieverse goes next.

Darkiss caused the Great Mash-up. No one knows what happened to him, but his henchmen were rounded up and sent to prison. One of them has been released. Her name is Tabitha aka Poison Princess.

Tabitha and her new coworker, Henry hit it off right away. Henry got mashed with an opossum. Don't call Tabitha "Princess". Not unless you want her to throat punch you. Henry learned this the hard way. With some help from his brother, Tabitha forgave Henry.

I laughed when after Henry and Tabitha shared an intimate moment commented with the following:

Henry "That was highly enjoyable"
Tabitha "I would like more in the future, yes"

Ok, if you had told me that opossums could be desirable, I would have said you were full of it. I am changed after reading this book. Call it a tail thing. Henry and Tabitha were all over each other. Going at it like animals (pun intended). I love this universe of characters that Sylvia has created. I am Team Mashies!

Thank you Sylvia Morrow for sending me this advance review copy for free. I am leaving this review voluntarily.

I loved this one a lot more than Goat Girl! We got to dig into the worldbuilding a bit more and the first book makes a lot more sense to me now.

I really liked Tabitha's poison skin issues, and it made things hard for her while giving plenty of opportunities for some really unique situations. Henry was just adorable and the sweetest guy ever. I think he is a great match for her, and I love a guy with a tail!

This was a quick afternoon read, and I think it would be a fun one to toss in your bag to read on the go. It's not super deep, and and you can easily put it down and pick it back up.

Overall it still felt a little rushed, but I still really enjoyed it. This is one you want to check out the TW list on, because it gets a little dark at times.

I didn't think I'd rate this book a 5 star read but here we are.

I don't wanna be biased that this book is good because the playlist I played while reading the last 35% of the book is fitting the theme, but I have to address it here.

I enjoyed every alphabet that Sylvia Morrow wrote in this book, I hope I'm exaggerating but I'm not.

Sylvia Morrow wrote this book while hugging and cooking soul food for every character, then affirmating each one, "Let's eat, and leave no crumbs!"

Tldr, Sylvia Morrow love the plot, the character, and the world building and it shows by how I enjoyed and love this book.

It's very rare I enjoyed reading a book where the writers clearly enjoyed writing the whole book. Sylvia Morrow, I hope every preferred beverages you drink will always taste excellent.

Ok, I loved this one ever more than the first!
Tabitha was experimented on and is now part poison dart frog. Created to be a villain she faces a lot of animosity. Not to mention being unable to touch anyone without causing egregious harm/death.
Reintroduced to the real world after prison she’s on the hunt for a new job. One Milly happily provides! She meets her new half opossum coworker Henry, an eager good boy who is dying to get closer. As it should turn out, he’s the only one able to touch her - and touch her he DOES indeed 🥵

Releasing 2/10 - pre order now! 💕

Not my usual type of read but was pleasantly surprised by the plot.

This is the second book of the Mashiverse where a villian mashed people up. This is the story of Tabitha, or Poison Princess, and Henry, a possum Mashie. This kind of reminded me of Rogue from X-Men with the whole not being able to fully touch people but Tabitha shies away from every and dresses head to toe in order not to poison any one.

Overall a good novella with decent plot.

I love action adventure with my romance! In this tale we follow Tabitha, our FMC, as she navigates getting back into society after being in prison for being the villain Poison Princess. She gets a job where she meets Henry, a possum mashie who is immune to her poisonous touch. They become a couple and they work really hard to keep it a secret to protect Henry from the evil government. But the secret gets out and Tabitha once again must take up het mantle as the Poison Princess to rescue him.

Read books one and two back to back, and I actually loved this one more than the first. The whole semi-reformed villain thing. Even tho she was more a vigilante and didn't have a choice based on the whole being experimented on and forced to have deadly toxins coursing through her. Like who's gonna be mad at her for going after the people who did that? I enjoyed her being able to be delicate and vulnerable with her possum..and him playing possum at the worst time, hilarious.

This is such an interesting take on the superhero romance genre!

I love that this is a higher paced story compared to goat girl, really picking up speed into some potentially interesting plot directions!

Tabitha is so grumpy, but is only soft for Henry; and Henry is such a precious little sunshine possum.

Yes if: Supervillains deserve love too

No if: Poison dart frogs give you the ick
