The perfect summer romance in a beautiful setting!
Format: Kindle
I give this book 4.75 stars rounded up to five for the purposes of this review. I really liked this story and flew through! Anyone looking for a great summer romance can find it here. This was my first Carley Fortune book, but I’d like to read more (and plan to read the sequel to this one very soon).
It was so fun to experience Percy and Sam’s relationship as it developed from close friends at the age of thirteen to something much more as they got older. Their relationship was so deep and respectful. They knew everything about each other and shared so many wonderful experiences together. It felt like a very natural evolution from friendship to romance (although I did want to smack Sam a couple times, but he was young, so I’ll give him a pass). And the setting of Barry’s Bay was a beautiful, relaxing place. I wish I could live in a cabin on that lake! There were some great side characters in this book too. Sue was such a kind, loving person. Charlie was sometimes difficult to like, but he really wasn’t a bad person. Delilah definitely annoyed me at times, but she turned out to be such a good friend to Percy. I wish we’d gotten a little bit more of Chantal, because she also seemed like an amazing friend.
I don’t always like a miscommunication trope in terms of breakups in romances, but this one actually made sense, because Percy and Sam were so young and trying to figure themselves out, as well as their romantic relationship. So, that part of it didn’t turn me off the overall story. I loved the ending (it made me cry), although I wish Sue’s storyline could have been different.
In my opinion, this was the perfect summer romance, so if that’s what you’re looking for, I would definitely encourage you to read it!

Sam + Percy 💕
Format: Kindle
Every Summer After is a perfect summer read and although it had been in my TBR for so long, I really enjoyed it. I’m a sucker for second chance romance and childhood friends to lovers and I was captivated immediately. Their friendship blossomed into a cute young love romance until one impulsive decision during a vulnerable moment lead to the downfall of Sam & Percy’s relationship.
Now over a decade later, Percy makes the trip back to the lake to attend a funeral and memories flood back of her summers with Sam. But does time heal all wounds? Read to find out.
I really love young love romances because they are innocent with heighten emotions, personal growths and can be extremely messy. Not to mention the angst that keeps me wanting to read more and this book definitely kept me engaged.

Warm Blanket Read
Format: Paperback
Wow, I didn’t know how much I needed this and I inhaled it. I needed to feel a bit of summer. I needed a small town. What I didn’t know I needed was a big love story. This was perfect and escapist. A perfect read to make you feel good and characters to swoon over. Can’t wait for the show now.

Heartfelt and Nostalgic
Format: Paperback
What can I say to effectively capture the beauty, sweetness, and depth of this story?
Sam and Percy’s story is sweet and nostalgic, and it made me feel like I was a teenager again right along with them. It brought back memories of my own teenage years spent camping at various lakes with family and friends; memories I hadn’t thought about in awhile.
Barry’s Bay is a character in its own right as well, and I had such a vivid picture in my mind of what it must have looked like.
There were moments when I laughed out loud, and moments that made me cry. The exploration of guilt and what it does to a person and the ones they love was so emotional and real.
And the sweetness and love between Percy and Sam, despite all their mistakes and miscommunications, is something that will stick with me for a long time.
There is so much heart in this story. I love a good friends-to-lovers romance, and have read quite a few, but this is easily one of the best.

Cute little read
Format: Paperback
I thought this book was a good quick read!
Plot: 4⭐️ I won’t spoil it but there is a trope I wasn’t fond of in this toward the end of the book, BUT it’s a very realistic response to the situation. (I am not making it okay in ANY means). I do wish there would have been a little more fun memories between them as friends.
Characters: I think Carly did a great job keeping the characters realistic. Yes the FMC parents had some money but it was a refresher that nobody was spoiled and the MMC earned his way into medical school.
