Sinful Obsession: A Billionaire Workplace Romance
Paige
I’d worked for Declan Brooks for years before I’d ever seen him smile. A real smile, not the kind he gave to board members or associates. The one that made me forget how to breathe.
He wasn’t an easy man to work for. He demanded structure. Control. His warmest mood was still cold, and most assistants quit within a week.
Not me. I stayed. I needed the job…and somewhere between scheduling his life and memorizing his preferences, I started to understand him.
When my relationship fell apart, I thought I could keep things professional, keep things the way they always were.
Then Declan offered me a place to land.
It was kind. Unexpected. Completely unlike him.
And with us so close, I found myself falling for the man behind the reputation.
Declan
I had never understood people. They were too loud, had too many expectations.
Paige Adams was supposed to be temporary, just another name from an agency I paid.
But she stayed.
She learned what I needed without me having to ask.
She understood me when no one else had.
For seven years, I kept my distance, convinced I could admire her from afar and that would be enough.
Then her world fell apart, and I couldn’t let her shatter with it.
So, I offered her help—a place to stay, close to me.
But she’s too close.
Too perfect.
And I crossed a line I shouldn’t have.
If she ever found out what I’d done, what I had hidden, I would lose the only person who ever saw me for me.

We need to have an option for 6 stars, 10 stars, or infinity stars!
Oh my goodness, this is the best book I’ve read so far.
Declan is coded in a way that my heart just can’t resist.
Pure perfection, no notes.
The things this man did to get his woman…
I think I need to switch jobs and become a PA as well.
Highly recommend Sinful Obsession!

Sinful Obsession is the newest romance novel from Julia! I enjoyed this just as much as Mine To Love (Aster Series). It has a similar enemies-to-lovers premise, but with a completely different backdrop and a broader variety of characters. It also has a Fifty Shades of Grey vibe, but with much stronger writing. The spicy scenes were not as prominent as in the Aster Series, which felt intentional and made the plot and relationship more realistic.
The side characters were lovable, which is par for the course with Julia's writing. However, I wanted to see more character development for Aunt Lisa, Uncle Eric, Riggs, Sam, and Dean. (A nice nod to Supernatural with the character names, btw.) Their personalities shone through, but I wanted to know more about their backstories and current lives. Perhaps this means they’ll be featured in future books? 😏
This was a fast-paced read that held my attention. I've never read a billionaire romance novel before, but now I'm hooked. Great job, Julia! 🌻
Overall rating: 5/5 ⭐️
Spice rating: 5/5 🌶

Julia doesn't disappoint
This is the 4th book of theirs that I have read and each one leaves me wanting more! It's funny, sweet, spicy, and without giving spoilers makes you hate how much you love the male main character 😂
10/10- if you haven't read their other books, please do so! You won't regret it ❤️
