One of Goodreads’ top 10 books of 2025, Ali Hazelwood’s latest romance follows a competitive diver and an ace swimmer as they tread forbidden waters.

Typically $20, you can grab the paperback for only $8.09 during October Prime Day.

The queen of contemporary romance, Abby Jimenez has done it again with Say You’ll Remember Me, published earlier this year. It has an average of over 4 stars on Good Reads and is currently number six on the list of the most popular 2025 releases. A feel-good read, it follows veterinarian Dr. Xavier Rush and social media manager Samantha Diaz, who fall in love but are separated when Samantha moves to care for her mother with dementia. The hardcover version is currently just $10.98 at Amazon for October Prime Day — a total steal.

Best October Prime Day Kindle book deal
Why we like it
The Perfect Divorce is another Goodreads favorite of 2025. From Jeneva Rose, the author of the multimillion-copy bestselling thriller The Perfect Marriage, it’s the second in the series and picks up eleven years after high-powered attorney Sarah Morgan defended her husband, Adam, against murder charges. It’s filled with page-turning suspense and plenty of twists and turns, which is hardly surprising if you read the first book. If you have a Kindle device — or don’t mind reading on your phone or tablet — you can pick up a digital copy for less than $2 during the Prime Big Deal Days sale.
