Scarlett Wallace has hated me since the moment we met.
Fine—feelings are mutual.
When she transfers to Shadow Valley U, her dad’s brilliant idea has us living under the same roof as newly minted step-siblings, and she becomes impossible to ignore.
Too stubborn. Too tempting. Too off-limits.
But when I mess up with the wrong crowd, they demand repayment. and unfortunately, they decide Scarlett is the perfect leverage.
She deserves a fresh start after what happened at her last school… Instead, she gets me—her stepbrother. The guy who can’t stay out of trouble…and can’t stay away from her.
Protecting her means crossing every line.
Wanting her means destroying the rest.
Cross the Line is a spicy new adult romance featuring a fighter and his brand new enemy (AKA step-sister), brought to you by the bestselling authors S. Massery and SJ Sylvis.


Scarlett is a temptation I can’t afford.
I love and I mean LOVE this series. And while I definitely still enjoyed this book, it just didn’t hit for me like the rest of the series has. I sat on my rating for a few days, trying to decide on a 3 star or 4 stars. I liked it more than a run of the mill 3 star read, but I also didn’t feel it packed the punch I would expect for a solid 4. So halfway we meet with 3 and a half.
Now I love a good step sibling trope, especially when it’s enemies to lovers with a splash of the bully trope. I mean YUM!
You asshole,” she bites out.
“Obviously. But an asshole who can make you come.” I lean over her. “Did you see stars?”
She grimaces. “That’s that, then.”
What’s interesting here is that I read the book in one sitting and it kept me engaged form cover to cover, but it also didn’t fully connect with me. It’s like all the ingredients were there but something was still off. I can’t tell you exactly what but there was just something missing. I loved Cross as a character, but I also felt like I didn’t know him enough. I felt the same with Scarlett. The chemistry was also there, but not enough to feel their true connection beyond surface level attraction.
They hate each other from their first meeting at their parents wedding, but I never really fully understood why. Cross’s severe dislike of Scarlett felt excessive to understand. Like a distaste, sure. But the level of hate he had for her and the way he antagonizes and borderline bullies her for it, not really. It just never clicked.
I think I would have loved the story as a duet or perhaps if it had 100-150 more pages to it. It just felt like we went from beginning to finish without a middle, if that makes sense. They hate each other for so long and I loved the slow burn of it. But then the romance felt sudden and the love element too early. The ending felt a bit rushed and while it was satisfying on the one side, it also wasn’t.
I genuinely don’t even know how to describe my experience with this book. Because I enjoyed it, but when I compare it to the first two books, it just didn’t hit the same. Would I recommend it for fans of this series? Without a doubt. It was a fun, sexy read and who doesn’t love a fighter MMC? Yes please and thank you. I may have let my expectations get the best of me with this one so definitely don’t let my rating deter you. It was a fun ride and definitely one I recommend. I can’t wait for the next in the series!
