A previous cover edition for this ASIN can be found here

I’m stuck with my brother’s grumpy best friend who is now my billionaire boss.


Having Kyle Gallagher around as my brother’s best friend was easy.

But having him as my grumpy billionaire boss is a nightmare.



The cherry on top is that my housing arrangements fell through,

Meaning I’m stuck with him at home too.



A major problem slowly emerges though.

His eyes look through my soul.



His voice makes my heart skip a beat.

His prominent bulge makes me weak in the knees.



As we spend more time together, the boundaries between us blur.

The forbidden desire becomes impossible to ignore.



Evenings shared at home deepen our bond.

Our teasing banter turns into heated moments.



His protective nature makes me feel safe,

Making my heart ache to be with him.



If my brother discovers our secret, it could destroy my career.

But this bad boy might be worth the risk.

Making Her Dreams Come True -
Alyssa had been crushing on her older brother’s best friend since high school and never told him, so seeing him again years later as adults, reignited all her old feelings, but she tried to keep it all in check, as he was now her boss. The last time Kyle saw Alyssa, she was sixteen years old and treated her as the kid she was, but everything changed when he saw her on the furs5 day of her new job, when she was all grown up.

Alyssa and Kyle tried their best to maintain a professional relationship, but the sparks between them ignited when she had to take care of him after the accident, which led to other stolen moments. Even though Alyssa and Kyle had tried to keep their budding romance a secret, they were caught in a compromising position by Alyssa’s older brother, which led to an awkward situation. Unfortunately, Kyle’s insecurities caused him to nearly destroyed their relationship, but he quickly realised the error of his ways and declared his true feelings towards Alyssa before he lost her.

The was a really enjoyable story, filled with drama, emotion and some angst, but most importantly a lot of love. I was hooked on this page turner from the beginning and didn’t take any breaks, until I read the last word. This is the first book I have read£ from this author and it has left me looking forward to more of her books.

I received a copy of this book free and I am voluntarily leaving a review.

I loved this novella!! It had everything a good story needs..A grumpy MMC, A sassy FMC and a brother who pushes them away from each other. Granted we don't know any reason Josh wanted to keep them separate except that he sees Kyle as a bad boy/player and he sees Alyssa as the young child..instead of seeing Kyle as someone who has grew as he got older and Alyssa as someone who knows her own mind and isn't afraid to work hard to accomplish her goals and she isn't afraid to be with Kyle. Will Josh succeed in keeping them apart or will Kyle and Alyssa take matters into their own hands??
I do wish there was an epilogue just to see how things were going for Kyle and Alyssa down the road.

Alyssa was sent to NY to fix the problem with Gall’s Restaurant. She certainly didn’t realize that it needs major help. She just needed to stay away from her brother’s best friend Kyle. Kyle can see that Alyssa is all grown up. But he can’t let his interest in her show. She is a great access to the business but never cross the line. This is an ok story. It is a bit choppy in some parts and it did drag at times. The chemistry between these two felt sort of off. I mean at times they talked and acted like siblings. But is does build up.

A great story. A few jumps in the story and rushed at the end, but a great, fast read. Easy to love the characters. Would like more depth into the other characters, especially why Josh doesn't want the MMC and FMC together. No glaring grammar or editorial issues. Would definitely read more from this author.

It's a good story. The characters are relatable and likable. There is angst from both the boss/employee angle and the bother/best friend angle. I'm not sure why Josh had such a problem. It was as if he didn't even like Kyle in the first place. I wish the story had more depth.

It was good just short no real development of the character. Explaining just brothers best friend that she had a crush on growing up.
