Charming and Summery, But Longer Than It Should Be
Format: Paperback
⭐️⭐️⭐️💫 (3.5 Stars) I listened to Every Summer After on audio, and at first, it really felt like it had the potential to be a solid 4-star read for me. The beginning is charming, easy to sink into, and definitely has that cozy, nostalgic summer atmosphere that so many readers love. It’s a cute, pleasant story with a smooth flow, and the type of book you can listen to without needing to focus too deeply. However, as the story went on, the pacing became a real issue. At around ten hours, this audiobook felt unnecessarily long. The plot didn’t have enough depth or twists to justify that length, and I honestly think it would have been a much stronger book if it wrapped up closer to the seven-hour mark. Around the midpoint, I found myself losing interest at times simply because the narrative stretched itself thin. When it comes to the writing itself, Carley Fortune keeps things very simple. There’s nothing particularly inspiring, profound, or memorable about the prose. It’s straightforward and easy to follow, but it doesn’t stand out, and I wouldn’t say it’s developed enough to be considered a distinct “writing style.” It does the job, but it never elevates the story or adds emotional depth the way some authors can. I also didn’t fall deeply in love with the characters. They were fine, but not the type that stay with you after the book is over. Because the character connection never fully clicked for me, the slower pacing felt even more noticeable, and some of the emotional beats didn’t land as strongly as they were intended to. Overall, Every Summer After is an easy, pleasant listen — perfect if you’re looking for something light, summery, and uncomplicated. While the overly long runtime, very simple writing, and limited emotional connection kept it at 3.5 stars for me, it’s still a sweet story that delivers exactly what many readers look for in a nostalgic summer romance. I’m still open to exploring more of Carley Fortune’s books, and I’m curious to see how her other stories compare!

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!

A book that hugs back.
Format: Hardcover, Format: Hardcover
I picked this book for my brother-in-law when we were celebrating my sister’s pregnancy, and the title ‘Why a daughter needs a dad’ sealed the deal. The illustrations are beautiful and full of tenderness. The messages on each page are simple and meaningful. I could so clearly picture him reading it to his baby girl someday. It’s the kind of book that isn’t just read – it’s felt. A thoughtful gift for someone you love – especially during such a special season of life.
