Rate this book
She’s built a life on secrets.
He’s come to uncover the truth.

In Windsor Brooke, girls don’t just go missing…

They vanish without a trace—and the town pretends nothing is wrong.

FBI Agent Fox Anderson arrives expecting a routine investigation, but the deeper he digs, the more he realizes this sleepy mountain town is hiding something rotten. The sheriff’s department is fractured, witnesses are terrified, and someone is determined to keep the truth buried.

Then there’s Kate Millard.

Beautiful. Sharp. Guarded.
A successful boutique owner with too many questions—and a habit of appearing where she shouldn’t.

Kate claims she’s staying out of trouble, but Fox can feel it.

She knows more than she’s saying.

As the investigation turns deadly, Fox and Kate are forced into an uneasy partnership—one that quickly sparks into something neither of them can ignore. But attraction is dangerous when the killer is watching… and Kate’s secrets might be the very thing that puts her in the crosshairs.

Because in Windsor Brooke…

Trust can get you killed.

The Darkness Within is a gripping small-town romantic thriller packed with twists, slow-burn tension, and a killer you won’t see coming.

I did not like it and I’m gonna list why…

1. Bad Romance - At times(mostly), I felt Fox actually wasn’t in love with her. I didn’t even understand what he felt about her. Most of the time he was bulldozing his way into anything and he didn’t trust her. He literally implied that she’s a co-conspirator to the crime that was happening. I think he wanted to control her. The way he got mad whenever she mentioned any friends visiting her or whatever, it didn’t seem possessive.

2. FMC Portrayal - Let me tell you, when a FMC is given the profession of being an ‘Assassin’. I expect her to be a badass one, aware, knows how to keep a poker face, and not be dumb after suddenly ‘liking’ a guy. She was none of those for the entirety of the book.

3. Thriller & Romance - They were overpowering each other and not in a good way. None of them were done nicely. I was skipping through most of it.

4. Riggs - The police department of that town was so dumb including her tbh. Your partner doesn’t like you so why would you go somewhere remote with him and as soon as you reach there why wouldn’t you text anyone else about your whereabout. Her body was also not found.

5. The Sheriff - I loathe people like him. He should’ve gone to politics rather than being a Sheriff. The girls of your town were being raped by your deputy and you turned your back on the victims ? Didn’t even investigate any fucking thing. Didn’t do his job anyway otherwise. Always trying to close cases without proper investigation. And refused to search for Chloe when her chances of being alive or dead was 50-50, not that that should have mattered.

6. The culprit - It was too easy. From the very first thing about him that’s mentioned, it wasn’t that difficult to guess. Disgusting pig should rot in hell.

I liked how there were multiple POV’s.

Oh my goodness did I enjoy this book! There is a phenomenal thread of romance in this book while not being the main focus. A fantastic protective, serious, and playful start to a budding romance with nothing more than kissing.
FMC is a vigilante assassin (though there are hints of possible government ties) who goes all over the world for her missions. However when young girls go missing, with one showing up dead, in her hometown - FMC is unsettled.
With this threat to the happy, consistent life she's built and the feeling that she's being watched - FMC decides to go rogue and take the case into her own hands.
When a cocky but funny FBI agent shows up to take over the case, a tense but passionate rivalry begins between FMC and the male FBI agent. She's always a step ahead and stays just out of his very intrigued grasp.

There's such a great thriller and mystery plot to the book with a lovely, sweet beginning to a love story. I want so much more of this!!

There's a killer dont have to tell me twice... I dont know what it is about books with killers? I have to read them.... What i loved most about this book was I couldn't guess who the killer was! If I can't guess who the killer is, then it's at least a 4 star read for me. I couldn't guess the killer in this. I'm pretty good at guessing the killer. it's rare that I find a book that stumps me.
It's definitely worth reading! I'm going to go back and read book 1 now.
I can't wait to read more!

The Darkness Within is book 2 in the AOD series. It's romantic suspense and slow burn.
I have to say, this one really keeps you guessing. I could not figure out who was doing the unaliving. Kate is such a strong female character. And I loved her and Fox together. Their chemistry was great and made the story that much more enjoyable. This one also has lots of twists and turns you don't see coming so make sure you buckle up for this ride!

The book was riddled with grammar and fact errors. At one point the mfc makes a point to stress that the lock on her gym locker couldn’t be broken into…that is utterly ridiculous. All locks can be broken, it is just a matter of how much time it takes. A GYM lock?

It was a bummer the author or editor didn’t fix these before, because the story was interesting enough and ended on a cliffhanger so I think I’m going to read the next one. Possibly against my better judgement… 🙃

This was a great thriller with a killer you can't wait to catch. Kate is a great character full of fight and intelligence. I really enjoyed the book and all the twists and turns. It is a well-written story and I hope to see more in the series!

Kate is a force to be reckon with. She is fearless it seems and honestly the best FMC I've read so far. I couldn't tell who the killer was through the book, which is rare for me but I loved it so much. I can't wait for more.

This book was so good, just when I thought I knew who the killer was there was a twist and I’m like whattt. Such a good book. I love the dynamic between Kate and Fox. I got frustrated with Kate but could understand her emotions. I can’t wait to read more from this author.
