    I just finished When We Believed in Mermaids. It was great!

    • Amber (Hip Sidekick)

      Glad to hear you enjoyed it, Casey! Thanks for the review!

    Kindle unlimited has been sooo awesome for me. I read a book a day or every two days, so it’s nice to not pay a fortune, or go to a library all the time. I like that as long as I have my phone, I have a good book. I read Urban fantasy, and sure it’s the junk food of the literary world, but it’s like Pringles: once you pop, you can’t stop. I’ve found so many enjoyable books and great authors. Also, many of those authors Gabe away their books for free during quarantine, which was super generous!!!♥️

    • Chelsey

      Yes! I’m a fast reader too so it’s awesome to not worry about paying for books. Although I’ve fallen in traps where the first book is Kindle Unlimited and the next 8 are not. 🤣 I recently started reading books by KF Breene but I’d love any recommendations you have!

  3. Toni Grant

    I’ve read most of those! I read about 8 to 10 books a week so Kindle Unlimited is my best friend. lol My favorite off that list is In An Instant. It’s not a hugs and cuddles feeling kind of book. It’s raw and emotional but it’s excellent.

    • Rebecca

      Man, In An Instant was a lot of feelings!

  4. Kate

    I did the free 2 months, and then when I went to cancel there was an offer to extend the free trial by a third month!

  5. Elise

    My colleague is writing a series, and the first book that just got published is Secrets of the Past: Year 1 (Ocean Academy). I know it is on Kindle Unlimited. It is a fun book, I definitely recommend it if you are looking for something to try 🙂

    • Amber (Hip Sidekick)

      Awesome! Thanks for the suggestion, Allie!
