Publisher's Summary

For years, the biggest threat that Yellowstone was thought to offer was in the form of its semi-dormant super volcano. Little did anyone realize the threat was real and slowly working its way to the surface, but not in the form of magma. Lying deep within the bowels of the Earth itself, an ancient virus waited. Recently credited with the extinction of Neanderthal man, the virus erupts into a crowded Yellowstone. The park is packed with sight seers and party goers during a benefit concert who are all now fodder for the ancient rage virus.

Follow along as park rangers and local sheriffs find themselves overwhelmed with a park full of infected human cannibals.

Pretty good start to the series.

Bob and his family are in Yellowstone to get away from everything and enjoy the peace and quite, but they didn't realise that there is a benefit concert on at the same time. Never the less, they decide to stay. While there, his daughter and son are messing in the water when they smell an awful smell. They quickly get out of the water. Later that night, the daughter starts to feel ill. She deteriorates rapidly and attacks her mother. Bob knows something isn't right because of her eyes and wrestles her down and ties her up. Bobs wife starts to feel ill soon after and disappears. Bob and his son go looking for her, but things take a horrible turn when it becomes obvious that she is heading to the benefit concert! Hundreds of people have no idea what is about to happen.

This was a solid start, to what I hope will be a great Zombie series. The book doesn't just focus on Bob and his family. We also meet the park rangers tasked with keeping the concert under control and a few other characters, all of whom converge at some point. I liked pretty much all the characters and found them easy to connect with. They were well written and developed and easy to like.

The plot was relatively fast paced. I liked that the author spent time on setting the scene and introducing the characters, before the zombies really start. I also liked how the virus came to be. It was a change from the normal, human error or intention that we see all the time. The virus was always there, it wiped out the Neanderthals and a simple shift in earth has caused it to resurface! It was a refreshing change!!

In all, this was a good read. On finishing it, I wanted to read the next one to see what happens the characters!! Hopefully the rest of them come to audio.

Johnny Mack read this well. He had plenty of tones and voices for the characters, and was clear and easy to listen to. The one complaint I had was that he didn't put enough into the performance to truly bring the story to life. I wanted a little more put into bringing the tenseness etc to life!!

Crazy and graphic fun!!!

What a start to a great series. Volcanos, zombies and metal. The premise was excellent. The action was fun and the horror was graphic and creepy.
The “zombies” were cool and vicious, as they should be. All in all, the story was well crafted and enjoyable.

The narration was done well. A little rough starting out but leveled out and was very easy to listen to.

Non stop action

Non stop action!
Johnny Mack did an amazing job narrating this book. I’ve already started book 2.
This is an action packed never slows down book. Buck our resident 12 year old boy is one of the smartest characters in this book. Skeeter may turn out to be one smart girl too but right now I’m seeing her manipulative side.
Curious as to how Candy will get through this. Hoping for the best for all of the characters.
Hey has anyone seen a naked crazy woman running around? 😜

Good old campy horror fun.

Story: Typical virus story that was fun and had interesting characters.

Structure: I found nothing wrong with the style or way it was written. Easy to follow.

Narrator: Was fine and did not hear any errors. He had enough range where I could tell the characters about. Can work on his female characters a bit though.

A good start to a series.










This book is a good start for a series. The book centers on a family that is visiting Yellow Stone Park for a family vacation. The rangers are also dealing with a rock concert in a venue that was not designed for that number of people. There are several other characters that are dealing with the situation. There was a series of earthquakes that unleashes something that has been trapped for thousands of years. The daughter is turned into a zombie like creature, who infects the mother. The mother escapes the mobile home and starts infecting the concert goers. This book focuses on what happens before the infected get out of the Park.

Could be not as bad, in my opinion

Decent enough setting for a cool outbreak. Not the biggest fan of the character stories but they’re not the worst. Cool idea about where the virus became active but the narration sounded like he was speaking in comic sans which made the book sounds kind of silly and comical. I feel like i could get in to it if the narration was better fitting. Just my opinion, get a sample if possible and choose for yourself.

Caldera

Good beginning to the series. I'm curious about the differences between the people who are scratched and the ones who are bitten. I hope the author will explain it in future books. I've listened to this narrator before and his female voice work has improved. I received this audio book for free through Audiobook Boom for my unbiased review.

A bit short but entertaining

I was given this free review copy audio book at my request and have voluntarily left this review.

This is a 28 Days Later style of zombie apocalypse story. Fast, visceral, and entertaining. The narration was great by Johnny Mack and helped the story come alive. The story itself, was a bit short and kind of felt unfinished, but kept me wanting more.

Ok, i was wrong !

Truthfully I’m so tired of Zombies that if I took my time and read what this book is about I wouldn’t have gotten it.
But to my surprise the author Heath Stallcup have done such an amazing job with this book that every character in it feels so true, really beautiful writing and the narrator Johnny Mack perfectly completed the job, together they created a masterpiece which I’m happy to say that I enjoyed every moment of it, and I can’t wait for the next audiobook of this series to come out !

I fully recommend this book for All !!!

One can't second guess crazy people.

"One can't second guess crazy people."

Whilst in Europe, two scientists puzzle over why the samples of Neanderthal DNA are showing identical, and seemingly impossible, readings, a fund raising rock concert is is getting ready to explode music in Yellowstone Park. There, not for music but to enjoy quiet and the joys of nature, are Bill Martin, with his fishing gear and tent, and seperately, Bob, with his not-so-happy family in a giant camper van, loaned to him by his brother.
Both are going to experience far more than hot springs and bears.

Caldera is a great start to a new series with good, humourous dialogue and a well established basis of normality before everything starts to go wrong. But when it does, it does so big time, with established characters being swept away unexpectedly even as others struggle to survive.

The performance by Johnny Mack captures it all with a warm, well crafted reading, including individualized character voicings, and a pace closely matched to the text. The whole, narration and writing, make for a very human, exciting beginning to the apocalyptic series, one which this reader is looking forward to continuing.

My thanks to the rights holder of Camera 1, for freely gifting me with a complimentary copy, via Audiobook Boom. I often enjoy books of this genre but this one exceeded my expectations with it's warmth, good humour and, yes, a terrifying feeling of reality. Recommended.
