Believe it or not, Demonosity isn't my first Amanda Ashby book (that dubious distinction would go to Zombie Queen of Newbury High), so I'm a bit familiar with the usual adjectives that are thrown around when it comes to her books - humorous, light, quick, fun. Normally I'd agree, Ashby has a way of subverting the usual young adult paranormal tropes in a way that's good for a few laughs, but this time around? - I really didn't think Demonosity was all that funny. Tired, maybe, but not funny.

YA paranormal novels–specifically Ellen Schreiber’s Vampire Kisses series–are what made me a reader, so I’ll always have a soft spot for the genre. Sadly, the YA paranormal market dried up with the majority of Twilight mania. Such is the nature of fads. BUT LO, A MIRACLE: I got pointe

Fun, fun, fun! It was a pleasure to have a female heroine who is not also the damsel in distress, but the kick ass guardian instead. Add to the mix, an asexual male best friend who is a nerd but also a hottie! Kudos to Amanda Ashley for bending gender expectations and stereotypes. Don't get me wrong, there are definitely male hotties who are hormonally driven, but it's nice to have a lead character who is not constantly distracted by puberty. Cassidy (the heroine) is tasked with a seemingly impo ...more

Recommends it for: Fans of suspenseful choices you have to make with two brothers who love you.
Recommended to Magic Shop by:, public library.

This is my first book by Amanda Ashby and it was really good. I noticed her other books on Goodreads and thought they were interesting. So when I found this book at the library I was excited to read it. The plot was really good with its suspenful chapters, twists and turns, and etc. I thought the characters were great too. I loved Thomas. He. Ishtar have been a little harsh with Cassidy at the beginning, but he meant well. I didn't like Travis because he seemed to sketchy and I

This had the potential to be a cute novel.

That was what I was expecting it to be.

But for some reason, to me it just fell short.

I just couldn't get into the story. It felt way too rushed and the characters weren't developed enough to create attachments with. Because a good story makes you relate to the characters within it, but this one just wasn't doing it for me.

The backstory and the plotline had so much potential. The whole "the Black Rose has been interwoven throughout time again and again" s

I chose to start reading this book because it was recommendation that Goodreads gave me.Something that impressed me in this book is how the author, portrays the character. "'Cass, stop smiling. There is nothing pretty about my having to wear a pink hospital gown,' her dad grumbled an hour later, but Cassidy couldn't help it"(Ashby __) This shows that she's happy that her father is alright.If you red further on you'd understand. I think that a trait I can describe Cassidy is; caring. She cares fo ...more

I loved this book. It was a fun mix of teenage life and epic quest. Cass was a sweet, cool girl and I loved reading about her. Nash was my fave ever he was great.
In terms of how asexuality was portrayed in this book I was more or less pleasently surprised. I was worried at first that Nash would be your stereotypical genius asexual thinks other people are inferior but nope! Nash was really likable and real. He was definitely a real person, not a (tired and unfair) trope. My one complaint was that

2.5 stars. I wanted to like this book, and it was an enjoyable read, but there weren't any fresh ideas.

One thing that I loved was that Nash, the perfect guy, was NOT a love interest. However, that being the case, I didn't understand why it was necessary to describe his clothing every time he entered a scene. It was also entirely too convenient to have him be a genius (and if he was a genius, why didn't he skip high school? That's not a very smart choice, especially since he has social skills as

This was pretty interesting. If I'm being honest, I didn't really read the blurb before going into this one, so I wasn't quite sure where this was going. Cassidy is a great character and despite her indecisiveness, she actually is pretty good at making decisions.

Great characters in this book too. Nash was delightful and Thomas and Travis... Well... I always preferred Thomas, there was just something about him. While Travis was lovely as well, there is just something about him that was too good t

Demons, magic, knight warriors, ancient book, "a powerful ancient force", good vs evil, and a teenager, Cassidy, in the middle of it. With the help of his best friend Nash, a asexual (interesting trait), geek hottie and Thomas, a knight warrior, Cass will learn to kill demons and protect the black rose (the powerful force/essence), which turn out to be more complicated then she thought. Demonisity is a fast-paced paranormal adventure with a hint of sweet romance. The plot is fun. The characters ...more

This book was a little different from the others she's written- sure there's sword fighting & monsters but this one had time travel. I liked that! Cassidy is just a normal teenager who has trouble making decisions who gets thrown into the world of "The Black Rose" & has the biggest decision heaped upon her. Cassidy was easy to relate to, very likable to me. Thomas was pretty interesting himself, his shapeshifting was really cool. This book is full of laughs, magic, knights in (shining?) armor, f ...more

Demonosity is a humorous and entertaining Young Adult novel. It follows Cassidy, a girl who has to learn how to fight demons and overcome her indecisiveness or else the world as it is known could end. Ashby does an amazing job of presenting developed and relatable characters. The plot was fun, and the length of the novel was perfect. The only downside was that it was a bit gory for my taste. Overall 4.5/5 stars; readers who enjoy Demonosity would likely also be interested in Ashby's other books, ...more

Amanda Ashby’s DEMONOSITY, in which a sixteen year old girl’s life is turned upside down when she has to protect an ancient alchemist’s relic from two demon knight brothers, one of whom is good and one of them bad: the problem is she has no idea which is which.

This book was a great choice for my next mother/daughter read! I read a book with my daughter at least once a month. This was a perfect blend of sass, comedy, and intrigue. We both give it a great recommendation!

Thoroughly enjoyed Demonosity! Amanda Ashby never fails to tell an entertaining, funny, light paranormal with strong, likable characters. Nash, the heroine's sidekick, might be my favorite character yet. I'd love to see a sequel with him in the lead. If, like me, you get tired of the plethora of dark YA you should put Amanda on your must read authors list.

I read this book because it showed up on a list of books with asexual characters. Plotwise it was...acceptable. Character-wise...only a few of the characters seemed fleshed out. It seemed like it had more potential than what was realized.
Nash, as an asexual character, was all right? He didn't ring true to me but I can't put my finger on any reason why.

It was a funny and exciting book about a girl who just couldn't make up here mind on anything which really connects with a lot of young girls feeling alone, but it also had a bit of the impossible in it making it interesting and stressful for Cassidy(the main character).

It was an entertaining read. I enjoyed the story. One issue I had is it seemed to assume asexual also means aromantic. But other than that the ace representation was good.
Demonosity by Amanda Ashby was a really good book! I read it in a day, and it was easy to read. Cassidy, the main character, was relatable and easy to empathize with. I liked her best friend, Nash, and Celeste, who was the unknowing vessel of the Black Rose. As for Travis and Thomas, well, I liked how it worked out, and there were twists I didn't see coming.

Amanda Ashby's Demonosity is an action novel featuring demons, sword fights, time travel, and immortality. Although including interesting plot twists and a suspenseful storyline, Demonosity resembles almost every other fast-paced book before it, only lacking a satisfying conclusion to the character's part within the story.
The book follows Thomas, a young knight from 1310 France, and Cassidy Carter-Lewis, a sixteen-year-old in present day California. When the Black Rose, the essence that grants i

*Big spoilers in the spoiler links so don't click if you don't want to know what happens!

When debating whether or not to give it 3 or 4 stars, I was leaning more towards 3 because I sort of dropped off reading the book near the middle for a day and wasn't excited about starting where I left off. Though I'm glad that I got back into after a chapter or 2, I still felt a 3 was appropriate. I enjoyed reading it, but (as one has mentioned already) it does has its flaws.

So I’ve read and loved two other books by this author ( Zombie Queen of Newbury High and Fairy Bad Day ) so I was super excited to read Demonosity and had very high expectations for it. Unfortunately, it didn’t meet all those high expectations. But it was still enjoyable, nonetheless.

The story itself was... just okay. I did love that they had to protect Celeste, the most popular girl in school who isn’t very nice. What a chore, but oh-so hilarious! I also lov
I first stumbled upon this author when I read her book, Fairy Bad Day, and instantly fell in love. She writes fantasy stories set in the real world, so even if the "always constantly in mortal danger" parts of her books aren't relatable, the normal high school drama is. This book was cute with an interesting, original story and many twists and turns. Cassidy is relatable, and can be frustrating at times, but is a good character and person. She desperately loves her father and best friend, while ...more

It's 2.5 actually.

I want to like you. I do. It was going well, dearie. It was. But then the last third part of the book happened and it became hurried... Well, not really hurried but the way things fell through confused and bugged the hell out of me since how come she suddenly had this thing for Thomas when she (and he) didn't give so much an indication that she liked him other than her fascination for his scar and wanting to touch.

There is a prophecy, secret societies, a quirky fun protagonist, well rounded secondary characters.
Family, friendship, and love get equal time there is no plot point that over takes the others.

With a heroine that’s a little exasperating, what with her indecisiveness and her tendency to get mushy-headed when a handsome boy starts paying attention to her, Cassidy Carter-Lewis is not one of the more appealing characters. Her best friend is also asexual (by his definition) and a lover of the Renaissance. How convenient that he specializes in ancient books and astronomy! This makes him rather unbelievable, although very useful when needed.
