When I was a wee one, one of my nightmares was being chased by animals - their teeth and fangs bared, their mouths covered with foam, their hair and fur on end. There was something about being the prey by such creatures (small and big ones alike) that was traumatizing. Imagine being chased by an aggressive squirrel, or by a hate-filled cat, or by hissing porcupines, or by crazy deers, or by mad beavers. They're supposedly friendly, amiable creatures - harmless to mankind - and to have their beha ...more
Initial reaction: A solid 5-star read from my first experience with Robert Lettrick. "Frenzy" is equal parts enthralling for adventure, survival and horror after an outbreak at a camp turns the animals wild, and equal parts humor and engaging for the characters presented and how they take it upon themselves to survive. I was really impressed with this middle-grade work and would highly recommend it.

I really enjoyed this one!

14-y-o Heath goes to this camp in the woods, where there's no cell phones allowed. He has some friends like Cricket, who gained his nickname because he knows a lot of bug-related things. And then there's his cabin-mate Will, who is this very clever boy who always has hidden agendas. And then, all the wood animals start to go crazy, with this mutated virus and they start killing people, even boys and girls. So this group of friends (and sort of enemies) have to escape to

If When Animals Attack and When Good Pets Go Bad had a lovechild, it would be Frenzy. Forget about a zombie apocalypse, you need to be more worried about Bambi and Rover chomping at your jugular.

Heath is spending the summer at Camp Harmony. Hanging out with his pals, avoiding the camp bullies, trying to ignore crushing feels for a girl, all seems pretty normal at good old camp. Until the porcupine incident.

Suddenly, an apparently rabid porcupine attacks one of the campers. It doesn't stop ther

I described this book to a book club recently. "Rabid animals attack a summer camp. Lots of kids die." None of them could believe it was middle grade.

It was great, too. Watch out for squirrels though!

This is the book to put in the hands of a reluctant reader for sure. Intense, fast paced, creepy, packed with animal facts and humor, this scary book is heart warming all at the same time. I'll be looking at squirrels in a whole new way from now on.

Gr 5-12 -- Good old Camp Harmony. Horseback riding, archery, crafts, and waterskiing on the crystal-clear Dray River. But the card games and squirt gun battles screech to a halt when campers are attacked by an apparently rabid porcupine, followed by a pack of wolves, the camp horses, and every mammal in the vicinity. A small group of kids takes to the river to escape the deadly critters, and each character’s strengths and weaknesses are revealed as the group struggles to survive.

To see my full review:

What would happen if the landdwelling animals of the world suddenly lost their fear or ever their love of humans and began outright attacking us? It would be like a zombie apocalypse, but with animals... and that's exactly what Lettrick pens in his exciting novel, Frenzy.

With an airborne virus that spreads an altered version of rabies, animals of all shapes and sizes are infected, shedding their fears and lusting for blood--mainly, t

Heath and a Group of friends, Cricket, Dunbar, Will the 2 Em's and others, wanted to get out of the forest. A few days after coming to a camp they are attacked by all the animals in the whole surrounding forest which means thousands. The animals have a much more lethal form of rabies that kills with one bite in seconds. As they leave the camp they have to wade through a deep river for miles. They found out that there was a swarm of tens of thousands of bats heading their way and the only way to ...more

Frenzy by Robert Lettrick is one of the freshest young-adult novels I've read in a very long time. Not dedicated to vampires or teenage sex, but rabid animals vs. humans and the survival of the fittest. I would suggest this to any fan of R. L. Stine, as a growing up horror novel. Terrifying in a good way.

My thoughts on this book were that I did not really like as much as I thought I would, and the reason for that was because I could not really find a main topic on what the story was about and that it also switched certain settings and topics quickly. Some reason on why I liked this book were because of how the characters interact with each other and how they react when something happens.

A feel good fluffy-cute squirrel story for the whole family to enjoy. NOT! It's even better than that - great friendship stories, smart kids with heart, with nonstop action and humor that makes you snort your cheetos. Robert Lettrick is a consummate entertainer and an artist of the written word.

Heath is an ordinary kid. his parents sent him to a camp called, Camp Harmony. it was all fun and games until a porcupine came chasing after one of the kids. to kill the porcupine Heath sprayed water on it, they thought that it just had rabies, but it was much, much worse. read this book to find out if Heath and his friends can get out of the frenzy.
A theme for this book is, "sometimes it takes sacrifices to live. " It is a little creepy but is perfect for this book. Because a lot of people- i

Unfortunately for Heath all that's about to change when the Animals suddenly start attacking everyone killing off most of the campers in mere minutes.

This was a fun, crazy, sad, uplifting, depressing story. Yep there were a roller coaster of emotions as what was to be a soothing summer camp experience goes horribly wrong. A government experiment gone wrong has the group running for their lives and their friends dying around them. Will they make it to safety or with they fall to the sick animals. Definitely worth the read to find out.

This was a fun, scary, creepy adventure story that is perfect for a middle grade audience who likes horror. It also carries some great themes regarding helping others through dire circumstances vs saving only yourself.

I liked a lot about this book. Excellent suspense and some real shocks. Also some interesting characters that the author helps us to know in a short time.
But, the ending left me wanting more. I felt like the author tied everything up too quickly and easily.

I actually liked this one a lot! I haven't read many zombie-esque books simply because I'd never thought that could be really written well. Boy was I wrong! The ending was a bit unsatisfying and there are holes I've been trying to fix after the fact but I would definitely recommend it to anyone!

Heath is glad to be spending the summer at a camp in the Cascade Mountains. He has some good friends, and gets along as well as possible with the oddly calculating Will and even manages to elude the evil bullies Thumper and Floaties. He's concerned when one of the campers kills a porcupine with a squirt gun, and the camp staff thinks the porcupine has rabies, but doesn't think much of it. Then, one day, all the animals start turning on humans, and when the humans are bitten, they die agonizing d ...more

I feel as though I am part of the unpopular opinion crew for this book. This is most definitely a middle grade novel, but it almost seemed too violent for a middle grade novel. I have come to really trust the media specialists that choose the Florida Sunshine State Book picks, but this felt out of character. The concept was certainly promising, a summer camp ravaged by rabid forest creatures. I was very excited to read this book. The execution of the story felt a bit clunky and the characters we ...more

I just read Frenzy and it was actually surprisingly intense and unexpectantly disturbing(?).
That doesn't mean it didn't have it's problems, however.

First big problem-the beginning. It was *this* close to being Goosebumps level of uninspired and cliché. I mean, Camp Harmony? Are you kidding me? How can something horrible NOT happen at a summer camp called "Camp Harmony"? Thankfully, it got a lot better pretty fast.
Also, the camp leader was incredibly cliché. Seriously. Thankfully, though (SPOI

I come back and reread this book all the time and every single time it manages to get better. The world and story building always stuns and leaves me breathless. Robert Lettrick makes sure that the story building is a constant element throughout his novels which allows you to constantly know where you are, what time it is and the progress of the characters. Storybuilding is something that I see a lot of authors struggle with, most of them only doing it when it’s convenient for the plot. Robert L ...more

I enjoyed reading this book. I enjoyed trying to figure out what kids had what motives, who would do what, who would live or who would die, and what next terrible thing was going to happen. I wondered how the 'frenzy' could ever be contained. I wondered if this was a lead up to a post-apocalyptic world.

I'll say that you don't quite know who is going to survive. As things happen, people get hurt or die that you didn't expect. The end of the book made me sad. I liked inferring details about the ch
