Faye, la Patata
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

Reading is my Escape
Scary Squirrels at Summer Camp Wow. I honestly did not expect to like this as much as I did. This book is scary, nail-biting, compassionate and somewhat realistic. But I am glad that my summer camp experiences were never this intense.
I don't want to give anything away, but I will say this is not for the faint of heart. There is a lot of death. There are a lot of crazy "rabid" animals. There are good kids and bad, brave kids and cowards, and there are a lot of slow revelations about the kids' ba

Imagine if the rabies went airborne, and all animals who get even a whiff of the infected oxygen, would get infected. Well that is the premise of this intruging read. Frenzy is meant for the YA audience, and takes them to a summer camp in which Heath and his friends are camping at summer camp. All is well until a bloody porquipine runs across the campsite foaming at the mouth and bites one of the kids there. They fall into the lake never to be seen again. Shortly after a rabid deer attacks the c ...more

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. ...more

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. ...more

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

Re-reading this book was almost like a new experience for me. It's been a few years since I last read this book. But this time I took thought of how the people actually got infected in the book. I noticed how there were weird purple stripes that grew along their body after they got bit by an animal. I would say that I sympathize for the characters the same way as I did the first time I read this book. It's much like some of the books I read today and how I sympathize for the characters.

And while he wants to. Get into a relationship at the start, things take an unexpected turn for the worst when the animals began uniting against the campers, and suddenly, Heath has to learn to trust his camper Will, who was proven to be anything BUT trustworthy.

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.

I got my son to do a little book club with me and a few other books, and at first he hated it. He had been asking to read this book for awhile, so when I finally let them read it, he was so excited. At first I thought there would be a lot of death in it, and it did. There were lots of unanswered questions and misspelled things. Overall, the book was interesting, I guess.

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!

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.
