• “I read this book in about 5 hours, I could not put it down from the moment I started it! It's one of those stories that work best the less you know going into it. The characters are endearing and the twists are genuinely surprising - it literally kept surprising me until the last page! A great suspense thriller with important themes of faith and redemption. Highly recommended!”

  • "This has always been my favorite kind of read. I have waited a long time for another book of this kind. I like that there’s more adventure and mystery than romance. Mystery books have always been my favorite kind of read since I first started reading in grade school (Nancy Drew). And the Christian aspect is a must! Just curious when the next book will be coming out…."

  • Honestly, I’m not a big reader. I have never enjoyed books for as long as I can remember. This has been a total game changer. I didn’t want to stop reading it and I am totally amazed! With all of the twists and turns, the suspense, it’s completely engaging. I hope there is another book to follow!

  • The pace really picks up in Castle Reef 2, with lots of action, suspense, and twists & turns in the story! I loved how the characters developed in this book even further, learning more about their history and interaction with each other. It all ties together at the very end when a lot of unexpected things unfold for a major plot twist. You’ll just have to read it yourself to find out!!

  • Another amazing adventure in Castle Reef! The characters that grabbed our attention in the first Castle Reef installment again pull us in for more. This book, like the first, is hard to put down as we are constantly waiting to find out what will happen next. And, what happens next is often not what we expected, though some clues may have been in front of us all the time. This book is more great writing from Andrew B. Sampsel, leaving us hungering for book number 3!

  • Great follow up to the first book!! Love the characters and story line. Highly recommend!!!

  • This book is the second of the trilogy. I did get a little confused with all the technology wording in this book. The story is great but leaves you wanting the third book. Which will not be out for about six months.

  • Loved the first book, now with the sequel the story gets even better. It has mystery, faith, love, suspense. For me it's a page turner.

  • Castle Reef 2: bloodlines is a worthy follow-up to Andrew Sampsel's great predecessor. Officer Julie is an engaging protagonist supported by a good cast of well-rounded characters. I am fan of novels that do a good job at establishing a place, and bloodlines is certainly in that camp. This community feels like a real place that you could go visit this weekend. If you're looking for a new page turner that's filled with suspense and surprises, I recommend you pick up a copy of bloodlines today and start reading!

  • Bloodlines is a superb follow-up to Andrew Sampsel's first Castle Reef. It picks up where the original ended and steadily builds momentum with the addition of new characters and expanded plotline.

  • A spell-binding thriller that will keep you riveted to your seat. It incorporates all the elements of a gripping mystery novel---global terror groups, conspiracy and political corruption, AI microchips and frightening humanoids, mysterious shark attacks, hidden identities, counter terror-teams, suspense, rekindled romance, journeys toward faith and an epic struggle of good over evil. We read the entire book aloud and could hardly put it down!

  • The twist and turns in this novel are unexpected, and they compel you to keep reading until all its mysteries are unveiled. Once I started reading, I couldn’t put it down. I read it in a day.

  • Love the suspense and the accuracy of artificial intelligence in the world today. Nice to read a book that if my grandson were looking over my shoulder, it would be fine.

  • Keeps your attention from the very beginning. I love the characters and the story. I can’t wait to read more from this author.

Reviews for Castle Reef

“If you are looking for something good to read, I would recommend this book for any adult or young adult. I finished it in a couple of late nights and early mornings. I would have read it in one sitting, but life just doesn't stop when we find a good book. It kept me on my toes. I had no clue what would unfold. The characters are interesting & the plot is engaging with twists and turns. It is full of all the things that make a good book, and it is void of all of the things that compromise so many. I can't wait for more from this author!”
