Not forced or rushed
Format: Hardcover
I really liked this book. Hannah & Garrett’s story starts off like a typical smart girl tutors the jock to help him get though a class in college. But their stories are traumatic and the things that they have both had to overcome make this book so much more than your typical tutor/jock story. Garrett is sweet, cocky, funny and helps bring Hannah out of her shell in a refreshing way. Hannah is not meek or mild or quiet, she is strong because of her past but still a little unsure. Together their chemistry is hot and their relationship just sort of naturally unfolds. I really loved that it didn’t seem forced or rushed, it just happened as it should. Garrett’s story in particular hit very close for me so maybe that is why I felt connected to these characters so much. I am really looking forward to reading the rest of the series.

The Hype Train Goes 🚂
Format: Kindle
4.5⭐️ | 4🌶️ | 4🎧
I genuinely enjoyed this book! It’s been sitting on my TBR for ages, and with all the buzz surrounding it lately, I finally decided to hop on the hype train. Thankfully, this one absolutely delivered.
What surprised me most was how much depth this story had. Beneath the humor, hockey, and romance are some pretty heavy topics, and I thought Elle Kennedy handled them with a lot of care. Hannah’s journey in particular felt incredibly authentic, and I appreciated how thoughtfully the book approached her past trauma. This story felt like a safe space for survivors, never minimizing what she experienced while still allowing her healing and growth to shine through.
Garrett and Hannah were such a fun couple to follow. Their banter was hilarious, their chemistry was undeniable, and their relationship developed in a way that kept me completely invested. I loved watching them challenge each other, support each other, and slowly become exactly what the other person needed. The romance was sweet, the spice delivered, and the emotional moments hit when they needed to.
As a hockey fan, I also loved the sports aspect of the story. Hockey is one of the few sports I actually watch, so those scenes were especially enjoyable for me. But more than anything, I adored the sense of found family throughout the book. The friendships and team dynamics added so much heart and made the world feel lived in and welcoming.
The audiobook was solid overall. Christian Fox and Lorelei Avalon did a good job bringing the characters to life. Christian Fox was a standout for me, while Lorelei Avalon occasionally sounded a little robotic during certain scenes. It wasn’t enough to take away from my enjoyment, but it was distracting at times.
Overall, I can definitely see why so many readers love this book. It’s funny, emotional, spicy, and full of heart. I’m excited to continue with the rest of the series and spend more time with this group of characters! 💕⛸️🏒

Dreamy Hockey Men & Steamy Romance
Format: Audiobook
Loved this book! This book came up as one of my Amazon similars. As for contemporary, they must have an intriguing plot to hold my interest. I normally prefer Paranormal, Dystopian or Sci-fi romance or romantic suspense.
The blurb sounded appealing, so I decided to give it a chance. This was my first hockey romance. After reading this book, I'm now a fan of the genre. This story had everything in it that I loved. An intense, slow-built romance. A cocky guy, who didn't really do relationships until he meets the girl who brings him to his knees. Friends to lovers with a few games in between. Spicy love scenes and jealous. Most importantly, a driving plot with intense drama that had the perfect balance. But it wasn't childish or over the top.
I was over the moon when I recently learned that this book is becoming an adaptation for on Amazon. May 13th can't come fast enough.
This book was so good, I decided to check out book #3 in the series, The Score. All 4 books in the Spin off series blurbs sounded interesting. After book #3, I immediately read all the books in the spin-off. Book #1, The Deal is tied with The Play in the spin-off series as my favorite with The Risk in the spin-off being a close 2nd..
Another thing I like about her series is that they all the books are stand-alones. You can also read the books out of order. Each book is a separate couple, so you get a new story each time, alongside following the other characters that were introduced in previous books

Good Start
Format: Kindle
This was the first book in the "Off-Campus" series. Hannah Wells, a focused and reserved music student, and Garrett Graham, the confident captain of the college hockey team whose academic struggles threaten his future. When their paths cross through an unexpected agreement, a friendship begins that gradually deepens into something more meaningful. I normally read YA but I found that I liked both of these characters I also liked the secondary characters as well. This was a pretty good read and I see why it's a good series on prime. This book was well written with no errors in grammar or spelling. I am looking forward to reading the next book in this series.
