Like drinking dandelion wine- it grows on you over time
Format: Hardcover
I was not terribly engaged with this book initially. The writing was beautiful. Poetic. But it was easy to put down and did not compel me to pick the book up again. Yet I had been warned of this and had been told to stick with it - and the advice was good. There is a slow poetic build as the reader comes to know the town and swim in its nostalgic melancholy. Ultimately, the book was a beautiful read. Never gripping but reflective and perfect for a contemplative read. It is about the passing of time. Youth and our mortality. Our eccentricities as our strengths. It is a picture of a small town in 1928, in summer, if you were white and middle class. It is a time and place and yet somehow captures something universal about the nature of memory and an awareness of inevitable death. About life in its truest sense.

Great book!
Format: Paperback
This book was my first Alexandra Moody book and I didn’t know how I was going to like it, but it was amazing!
It kept me on the edge of my seat the whole time it was a perfect read for 12 and up, after this I bought more of her books!
Overall it was a clean and amazing read

great book!
so cute and driving, definitely pretty predictable but it’s a fun, in between books, or if you just don’t have anything to read, book. definitely recommend. its a little cheesy at times but it’s good overall. i did not like the main character 😭 she’s a little bit annoying and overly blind socially, but i liked Chase and he kept me reading. i will say it one again; i think it was a really good read and it’s pretty light-hearted and a good idea with the enemies-to-lovers thing. loved it!

Cheesy romance that hits you in all the feels.
A cheesy romance full of tropes but it pulls them off and keeps you smiling and rooting for the main characters the whole way through.
