Significantly Smarter...
ProIsoCharge delivers digitally controlled alternator output distribution while protecting the health of engine start batteries. An industry changing design that provides intelligent and zero voltage loss isolation, charging of up to 3 other battery banks off a single alternator (model specific). For dual engine applications, ProIsoCharge offers an exclusive 2 alternator input model with up to 4 battery banks. Smart enough to provide priority charging to a battery bank that's under load by taking fully charged batteries off line. The all-in-one design eliminates the need for multiple voltage sensitive relays to charge multiple battery banks simultaneously, saving space, installation time and cost. Ensuring fully charged batteries and faster charge times, ProIsocharge eliminates the typical alternator voltage loss of 0.6VDC that's commonly associated with traditional diode based isolators. Installed with the ProNauticP Series, a boat owner can enjoy the full benefit of shore power and on the water charging. Designed to provide more time on the water enjoying what you like most... boating.

Solid start to a new series! Love the Holland brothers
Format: Kindle
There is one thing I've learned when I read Rebecca books: I either love them and am obsessed (looking at you "Tutoring the Player") or I really like them, but feel like there's something missing. And this book fell in the latter. Ok, so, I did really enjoy this book. I was so excited to get to know the younger Hollands after meeting Hendrick in "Tempting the Player." I was so intrigued by their dynamics, so when I saw those Holland brothers were getting a series, I was SOLD. And I'm not gonna lie, I really enjoyed grumpy and closed-off Knox Holland. The relationship he has with his brothers is special, but especially the one he has with his youngest brother, Flynn. And that, alone, made me fall in love with him. But watching as Avery wore him down, without even trying, was the best. And how he didn't even realize it was happening? Even better. Avery was awesome! I LOVED her! She's had a rough go after an injury at the end of her freshman year at Valley U, and it's really rocked her confidence as she works to come back. She was funny and the way she fit in with the Holland brothers was perfect... especially the way she cared for Flynn. I loved the banter and way she goes back and forth with Brogan too. That guy is hilarious. She just...fits, and they all can see it. The only thing that kept this from a 5 star for me was that it just felt like it...ended. We have the conflict, we get back together, but then, it's a super quick last chapter, no epilogue, and it's over. I really wanted to see at least a little more of them as an official couple. I do love how you could see how close she and Flynn are in the last chapter. And how even though the others have moved on to other things (Archer and Brogan the NFL, Henny and Jane are married), they're still such a tight family unit. There is a super short but sweet epilogue you can get at the end of the book if you sign up for Rebecca's newsletter (which, duh, I already get because I do love her books!). Overall, I really enjoyed this book, but I have to say, the level of excitement I have for Archer and Flynn, but Archer especially, is next level!

I loved it so much!!!
Format: Kindle
I've had this one on my TBR lis forever and been meaning to get to it. Considering I picked up the ebook last year not long after it came out. I can't believe I let this one sit on my kindle for as long as I did. I ended up starting and finishing in just one afternoon absolutely hooked on Avery and Knox. They has this connection that just works even if they are to stubborn to see what's happening. I loved the whole bad buy meets the good girl in this sweet steamy enemies to lovers romance. The author does a beautiful job creating a captivating story with characters you can't help falling in love with. This is my first book by the author and I'm a fan as I enjoyed every moment of Avery and Knox's story. I loved that we get to know a little bit of Knox's brothers as the series is about them and can't wait to devour there stories too. Highly recommend the characters are engaging and the story is perfectly balanced with just the right amount of romance. This one made me want to look up the riding that Knox did off season and it's impressive. I loved it!!! One of my favorite books of 2025.

Good Sports Romance
Format: Kindle
Knox is a motor cross racer and Avery is a gymnast. Seems like opposites, right? But there is much more common ground. This couple is fantastic together and love the friends and family vibes. Can’t wait to read the rest of the books in the Holland Brothers series and go back to read Hendrick and Jane’s story.

Holland Brothers Series !!!
Format: Kindle
5/5 ⭐️ 2/5 🌶️ A Holland Brothers Series was exactly what i was hoping for since i read Tempting the Player. Rebecca gave us all exactly what we wanted a Holland brother series and kicked it off with Knox. Knox is the broody, grumpy, closed off, and the 2nd oldest brother who stepped up and held down the fort taking care of the younger brothers after their mom passed and dad stopped coming around but gave up his dreams/ wants in order to do so. With Hendrix, the oldest brother from TTP, back home Knox can go live out his dream as a pro motocross rider. After something goes down between him and his teammate, he’s left without a team and ends up back home and ends up asking the help of a friend of a friend to train him who is Avery. Avery is a college gymnast with two Olympic medals and last season she choked and injured herself before she was able to compete. She’s doesn’t want a distraction but agrees to train Knox which should be easy but it turns out to be anything but that. The banter and argue and then everything changing when his shirt comes off and she spends a little too much time admiring his body in a handstand. These two balanced each other out so well it’s hard to deny even to them. Overall i loved the plot and the character development between these two, the spice, the banter, the nicknames it was all just …..chefs kiss 💋. I cant wait to see which Holland brother Rebecca has in store for us next! 🏍️ Sports Romance 👑 Opposites Attract 🏍️Enemies to Lovers 👑 Train Together 🏍️ Banter 👑 Motorcross x Gymnast 🏍️ Bad Boy x Good Girl

What a Ride!
Format: Kindle
I thoroughly enjoyed this book! I was intrigued by the blurb, "Mississippi Delta," "haunted by her great grandmother's nanny," and the book was even better than I expected. I laughed out loud, shook my head at the accuracy of the descriptions of Southern culture, and even stopped from time to time to admire sentence structure and vocabulary choices. A satisfying read. I would recommend this book to anyone who enjoys unraveling a mystery with an unsuspecting hero.
