Review of advance copy
Very detailed independent read
I really enjoyed this book. I had not read the first two in the collection, but did not notice the lack at all, a very independent read. I enjoy the apocalyptic books, especially how different people handle the world-ending-as-they-knew-it situations. Cavern Sanctuary puts a different spin on it as a group of unlikely people form a family in a natural limestone cavern that protects them from the initial deadly affects of nuclear fallout.
Alex and her 3 children and 2 dogs move to a small campground in Florida in an old RV after the death of her husband due to the husband’s mother basically taking everything of her son’s, including their residence. At the campground Alex befriends the people who live there also and they all wind up forming a “family.” The campground owner and her adult child-like son, a mother with 3 young children, an elderly Swedish couple and a grumpy retired vet.
The group is warned of an imminent nuclear attack and given survival instructions that include a nearby cave system for shelter from the campground owner’s son who is high up in the military leadership in Washington DC. The story follows their struggles with post nuclear living and while looking for others to share their lives with they discover a town that seems well organized and safe from the outside, but on the inside it is a harsh dictatorship.
My only complaints about the book are: 1) overly descriptive and adjective using, tho on the plus side of that the author gets you to feel their emotional states very deeply. I admit to skimming a bit towards the end of the book, which leads to 2) repeated use of some minor phrases - that got kind of annoying after the 3rd or so use, even tho it was appropriately used and described the situation really well.
The story moves along at a good pace and keeps you turning the pages.

This was a solid 4.5 stars. I have had the pleasure of reading a few books by this author and I am blown away with the writing. This author knows how to capture all of the emotions and feels. I always have a hard time putting the books down.
This story is about survival, found family, sacrifice and catastrophic events. It had me crying and heartbroken at times. It had me cheering on the FMC, Alex, who is a nurse and mother trying to help her family and others during this nuclear fallout.
Alex, had recently lost her husband. All the while dealing with her grief and her children’s grief, they needed to pick up the pieces and to get away. She decided to take them to a campground and escape the everyday and never understanding what horrific events would soon play out.
She would soon meet some amazing people who would change her and her children’s lives. Her motherly instincts will kick in and nursing skills will play an important role in many people survival!
This story is so real and heartfelt. I highly recommend it. Sometimes we never know what we will do or how we will react when you have no choice or your back is against the wall.

A grieving widow is evicted and then the world falls apart with a nuclear war. A believable story (I was a Cold War Vulcan nuclear bomber pilot, so it rings true). At an all time low, she rises to various challenges. Fairly well written.
However, the mention of her dead husband’s watch every third page is well over the top for me. Yes, I understand the symbolism but it started to cause eye-rolls after the 100th time.
This is a standalone book, you do not need to read the first two books in the series.
Recommended: Yes.

Alex has lost her beloved husband and her mother in law has evicted her from her home. So with her three children, two dogs and a camper they are living. When the unbelievable happens and she must fight for everything she loves. I was so into this it felt like I was right in the middle. I couldn't stop reading and I didn't want to. It's a utterly brilliant survivalist story brimming with action.I received an advance review copy for free, and I am leaving this review voluntarily.

4.5. Wow - This book was a terrifying and emotional story of survival during an apocalyptic event and the difficult road to rebuild. It is a story of a woman who found her strength in the midst of several devastating events that are so overwhelming. It is an enjoyable read that grabs you at the beginning and does not let go until the very last page.

I did really enjoy this end of the world adventure! I like the main female character, it has interesting ideas & it is well written. I felt at moments that the energy slowed a little in the last quarter of the book. Overall a really good read! I do recommend.
