a perfect summer romance
Format: Paperback
this book was phenomenal!! i loved every page and i fell in love with the story and characters. it’s told in past and present timelines over the course of six summers and one weekend 12 years later. you get small town, second chance romance, childhood best friends to lovers to strangers to lovers, and more! some of my fav tropes in one book <3 i love the parallel events between the past and present chapters, seeing how percy and sam grown and matured but also stay the same throughout the years (iykyk - the friendship bracelets, “swear on it”, ice cream). their attraction and connection are undeniable! the book perfectly captures friendship, teenage angst, first love, loss, mistakes, and forgiveness. it’s also about finding your person, someone who understands you like no other.
the writing was spectacular - it was so magical and enchanting as it encapsulated summer nostalgia at a lakeside cottage. i felt like i experienced every summer with percy and sam. i love how real and relatable the characters are. percy and sam are two flawed characters that let their fears get in their way, but they try their best to repair what they broke. i adore sam so so much, he’s the sweetest and kindest guy who loves really hard. the sarcasm and banter between the two were soo good too, i loved how we get a glimpse of what they were like at 13 and then at 30.
this is the PERFECT summer read, i highly recommend it!! i promise you’ll love this if you love ‘love and other words’ by christina lauren! i didn’t think i’d find a book like laow that hits the same, but reading this book made my lil laow heart so happy 💞 i’m blown away by the fact that this is carley fortune’s debut novel and i hope there is more to come!

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.
