The writing its humorous and well suited for its target audience, yet it holds a sophistication that older readers will find enjoyable as well as leaving one with a reminder of good literature that we have encountered at the same age as the characters. There is also the added wonder of the unknown in the first few chapters that is as lovely as it can be frightening- how many books have captured that essence while injecting humor alongside it?

The easy familiarity of the opening chapters combined with engaging writing and original twists dragged me in and kept me glued to my computer. It all brought me back to my childhood and inspired the kind of wonder that is all too rare in most of today’s offerings. This is a great story for younger readers and an equally great story for those of us who grew up on Back to the Future, Goonies and Star Wars!

A strong opening that manages to capture that childhood wonder and feeling of adventure, without feeling in any way childish. I feel like even the little bit I have seen will be in my head for a long time, and now can only wait eagerly for more.A strong opening that manages to capture that childhood wonder and feeling of adventure, without feeling in any way childish.

Just from reading the first few chapters alone, Leone's descriptive writing style leaves that childhood smell of exploration and wonder clinging on the clothes of his characters, just as strongly as those characters and the true-to-life situations that surround  them clings to the reader's mind. This is a marvelous start to a marvelous book. And that leaves me to wonder: if only this little bit of Champions of the Third Planet can stay with me this strongly, what will stay with me when these kid and their story  are shot across the farthest reaches of outer space? How will the troubles they encounter on this little blue marble transform when they reach a whole new world? I can't wait to find out.

The opening chapter set the mood instantly, putting Milo's thoughts right into your head, with a few laughs as well. Quickly paced with a balance of wit and wonder, after reading the first chapter you will be ready to fight alien monsters. On a far-away planet. In order to save earth. This idea hits the very definition of space opera in every regard.

For what promises to be a thrilling adventure mystery, Champions of the Third Planet gives you precious little to draw you in, but will do so anyway. Rather than directly spelling out powers and abilities, the protagonist experiences the mystery along with the reader so that both are on the same journey.

Champions of the Third Planet is an intoxicating mix of a boys own adventure and Hunger Games set in outer space.  After stumbling onto a mysterious black orb  in the woods while fleeing the bullying Cobra gang, Milo's troubles are only just beginning.  The author brilliantly extrapolates the from the frying pan into the fire idiom.  Into something of intergalactic proportions.  Milo discovers the orb has transported him to a long dead planet, where, along with various other hapless aliens they must fight together to defeat the Champion for a chance to return home...for Milo, battling bullies back on Earth seems infinitely more bearable than gladiatorial battles with crab shelled lupine aliens.  A swift read of the initial chapters leaves me nursing an appetite for more...I've sated that thirst with a pre-order and I'd advise anybody wanting a great read to do the same.

A review by my son, Sam Berg, (he is 7-years-old): 'I really liked the descriptions, I could imagine everything clearly. I especially liked the part when he gets trapped in the orb, that was my favorite part. During the flashback of the bullying scenes, I understood how Milo felt and I was worried for him. I wanted to get back to the orb, but I still wanted to learn about the backstory. I didn't think the orb was creepy, just mysterious. I had some relief when the boys didn't find Milo, but I was eager to find out how they all get in the orb together. I liked the bully aspect in chapter 2, and I liked when Milo got trapped in the orb in chapter 3. I can't wait to read more!'

What's in the orb?? I want to know. This looks cool.

Exhilarating and Fun!
