wonderful
wonderful story line. excellent and likable characters. sure to keep the reader turning the pages find out what happens next!

From J. Kaye's Book Blog
Anthony J. Mirarchi has written an adventure `teen lit' series called Cristo's Chronicles. It is set on the island of Adolphia, in the Bronze Age, where the inhabitants do not have a counting nor writing system, nor currency or standards of weights. The sorcerers of the time were proto-scientists. It's a great, fast paced, adventure, learning series for grades 4 through 8.

For me, THE KING'S CHALLENGE was intriguing. How do you create a calendar without a writing system or even the names of numbers? It highlighted how much we take for granted some very basic systems our civilization is based on, namely math and writing. I can't tell you how old Cristo and Grigor are; there are no numbers in the book! However, they are pre-puberty, so 9 thru 12 would be the age group. Mirarchi did an outstanding job in showing how to count without even the names of numbers.

Outstanding!
It is refreshing to experience a novel designed for a young (and not so young!) intelligent reader.This book should be required reading at a middle school or grade school level.It provokes original thought, and takes the reader through a process of deduction.The cerebral nature of the book is such a refreshing change from the current mind numbing era of comic books and video games.This is a book that I would one day like to read along with my children.I look forward to the the author's next challenge:Book Two.

Great book for a young reading who likes science
The really fascinating thing about this book is that the hero Cristo does not discover a new magic item or go on a quest to kill a dragon, but instead learns new scientific principles and uses them to discover previously unknown things about the world.The main adversary wants the knowledge that Cristo possesses and that is where the adventure begins.

This book is great because it incorporates a clever new concept and does not use the same old formula.The author has obviously thought a lot about what it is like to live in the bronze age without written words or even knowing how to count.Imagine trying to tell a story when you can't even tell the reader how old the characters are, or how many sheep are in the flock.This book is a clever combination of adventure and learning which should stimulate many young readers and get them interested in science.

The King's Challenge
THE KING'S CHALLENGE is a story of teamwork and courage that enlightens readers to the merits of determination and loyalty. A fine message in any day or age!

It was refreshing to see the adults in the story giving Cristo's ideas and opinions their full consideration. Readers should be able to connect with how Cristo feels throughout the challenges he faces.

At first, I was a little concerned with the time setting but found I enjoyed the story immensely. I think a blend of the near fantasy with the reality of the Bronze Age would appeal to every young reader. The two were interwoven with great craftsmanship and in a manner I believe readers will find very interesting. ... Read more

By exploring some of the more important senses of time which were in circulation in the medieval world, scholars from a wide range of disciplines trace competing definitions and modes of temporality in the middle ages, explaining their influence upon life and culture. The issues explored include anachronism as a feature in earlier senses of time, perceptions of death and of the Last Judgement, time in literary narratives and in music, constructions of time as used in the professions, and original work on the particular systems and technologies which were used for the keeping of time, such as clocks and calendars.

A trek through time
This book takes us on a trek through time - literally. We learn about timekeeping from the calendars of the earliest civilizations all the way up to atomic clocks and beyond. I have to say that I got as much out of this book as my kids did. I had used terms like "quartz timing" or "atomic clock" before without really understanding what they are. The best part of the book for most kids will probably be the activities. My daughter loved the incense clock especially. None of the activities required any hard-to-get materials, and we look forward to trying more of them. I have to give special kudos to the extensive glossary as well. ... Read more
