It was a good read.
Format: Kindle
While I did enjoy the book, it moved a little fast with little plot development. Rose started strong and then she seemed to get weaker and weaker throughout. Even the parts where she found her back bone didn’t compare to her initial anger towards her family.
Lena was a good character. A little huffier than I liked but overall well rounded. Overall, I enjoyed the book, it just wasn’t my favorite.

Lovely sapphic vampire and human romance!
Format: Kindle
I was given an ARC copy of A Rose For The Taking by author Katie Trapp. Thank you Katie for the chance to be an ARC reader.
A Rose For the Taking is a sapphic vampire and human romance with topics of arranged marriage, self-discovery, and a little bit of mystery. Rose is a human, who is pressured by her family to enter an arranged marriage with a vampire, Lina. Lina is a vampire whose job is to maintain the peace between vampires and humans. With tensions rising between the two Lina agrees to marry a human in order to hopefully ease those tensions. Lina chooses Rose expecting to be friends, but nothing else. Instead love starts to blossom between the two as Rose learns to find her inner strength and stand up for herself, while Lina learns to open up her heart again. However, a threat causing the tension between the humans and vampires puts there love at risk as well.
The journey these two characters take is so relatable. Rose has been taught by her family to be subservient and basically have no voice. Lina has grown closed off in terms of romance due to her past experience. Together they go through a process of self discovery and fall in love during the process. They aren't perfect though with some ups and downs, which makes this story even more relatable.
This book has it all. There is growth of characters finding themselves, a spicy romance, and a little bit of mystery that blended together creates a story you don't want to put down till you finish it. I have read a few of Katie Trapp's books so far and each one has captured me in some way and just drawn me in. Katie has a way with words that you can somehow relate to the characters in one way or another. This one was no different and I enjoyed this book a lot. If you like vampire and human romance this is the book to read. I look forward to Katie's next book.

Ford.Grant. That is all
Format: Kindle
Umm ok so this was literally the most PERFECT thing. This book is special. These characters are special and beautiful, and so wonderful. So precious. I love them all. I love this book. I'm blown away.
You know those rare books that enchant you from the very first sentence, the ones that grab your heart and don’t let it go? THIS. This is one of those books. I adore this book with my entire heart. It was so utterly perfect in all the best and right ways. I honestly just wish I could go back and read this again for the first time because it was SO GOOD.
I devoured this in two days and was just absolutely giddy while reading about Ford and Rosie’s love story. I swear, Elsie Silver wrote my love language with these two. The sarcastic and witty exchanges between them is what I absolutely loved and couldn’t get enough of. Their attraction towards one another and the fact they were so clearly head over heels in love was undeniable and the tension between the two of them was so palpable that it gave me all the feels. My heart absolutely ached for these two, even when I was literally laughing out loud over their banter. And boy, the way they loved each other just swept me off my feet in my most favourite way.
I don’t know what my favourite part of this story was. There isn’t just one. There’s many. It’s all of it. There’s so much to it that if I was to really dive into it, I’d come out with an essay. All of that to say, I loved it. I really, really loved this story. Soul level and all the good stuff. I cannot say anything bad about this book. It’s up there as one of my all-time favourites and I love it with every fibre of my being. A million hats off to Elsie Silver for this one, because I know this is a story I’ll be thinking about for a long time. Elsie Silver can truly do no wrong. She is the blueprint, and I will read her books forever.

Banter and tension and a little storm cloud perfection
Format: Kindle
I'm convinced that Elsie Silver puts some sort of crack in her books.
They are always exciting and immediately grab you, especially with the characters. And Wild Love is no exception. Great characters all around with such a perfect journey to their HEA.
You know the kind of relationship you might have with a friend's younger sibling? The one where you're kind of mean but maybe deep down you like them? Like the juvenile antics of pulling the girl's ponytail on the playground when you are just a kid? THAT is Ford and Rosie! From when they were teens to even now as adults and I frickin loved the fire banter that gave them. These two are hilarious together, yet you could feel their tension was building up to something even more.
"That journal entry is fascinating, but all wrong. I was at home when you called that night. And I broke every speed limit to get to you."
While I absolutely loved Ford and Rosie's characters and the way they played off one another, I actually really liked another character and the relationship she had with both Rosie and Ford. And she's the little storm cloud that no one saw coming. She is the reason I initially fell for Ford from the first chapter. Because if you weren't already swooning at the very beginning of this story for Ford Grant, then this may not be the book for you. But the way this man steps up for a stranger claiming that she's his daughter and he just does 'the right thing' is unheard of. Maybe slightly unbelievable, but this is why we read romance and that is why there are Ford Grants. Because we see that decision is totally and 100% him over the course of the story. And that girl? Cora? She is the perfect character to upend his world for a time. Loved how they made their situation work and I loved how everything grew not only between the two of them, but also between her and Rosie. Small things became big things with these 3 and I couldn't have loved it more.
Elsie Silver gave us such a great start to a brand new series. The characters are sexy and hilarious and just work together perfectly. I cannot wait to continue with this series.
If you enjoy:
Single Dad
Small town
Frenemies to lovers
Best Friend's sister
with the best cast of characters that delivered great banter and sizzling chemistry, then Wild Love is THE book to pick up!
