One Sentence Review: Has some strong elements and would perhaps be more impressive if the villains' villainy were clearer and the entire enterprise didn't feel like a mix of A Wrinkle in Time and The Phantom Tollbooth.

Lost in Lexicon

It’s the middle of summer and Ivan and Daphne are bored. I guess being stuck at your aunt’s house that doesn’t have any electronics in it with your cousin is pretty boring; until our aunt sends you on a super awesome scavenger hunt in another dimension of course. In this first book of a series of two comes many challenges for Ivan and Daphne such as math problems, a plague of punctuation, a falling mountain, and most of all lost children. Will Ivan and Daphne fulfill the prophec

This is a wonderful book. Written with a basis similar to "The Phantom Tollbooth," but with more of a almost science fiction flair. Great read for an slightly advanced 5th grader or 6th grade and up. Intertwines wonderful algebra and sentence structure in a land of wonder and confusion. The characters Ivan and Daphne are superbly real and their intent and journey is honest and enrapturing. Look for it in October 2010!!

About the book: When thirteen-year-old cousins Ivan and Daphne go on a treasure hunt in the rain one summer day, they never expect to stumble into a whole new world where words and numbers run wild.

After the cousins outwit a plague of punctuation, grateful villagers beg them to find Lexicon’s missing children, who have been enticed away by dancing lights in the sky. Trekking between villages in search of clues, the cousins encounter a talking thesaurus, a fog of forgetting, the Mistress of Metap

Do your kids long for a good book they can sink their teeth in? ���Lost in Lexicon��� is perfect for readers who love a challenge.

Ivan and Daphne are spending a summer with Aunt Adelaide, a former librarian who casually leaves books lying around in various places to get the kids reading. The kids, however, had planned to have an ongoing monopoly game, hiking, climbing trees and rope swinging. Unfortunately, some rainy days got in the way. Aunt Adelaide sends the kids out to the barn on a treasur

If you have an aptitude for the written language and numerical equations, this book is for you. Even if not, it’s a whimsical look into another world, one ruled by peculiar laws and even more peculiar people. Here, being lost in a fog can quite literally cost you your memory and a walking thesaurus can be a cute llama-like creature instead of a tiresome boor. Much like The Phantom Tollbooth and Ella Minnow Pea, this is a romp through a world of wordplay that’s fun and erudite at the same time. I

Noyce has created a delightful pair of characters who, bored with the lack of entertainment at their Aunt's house on a rainy day, explore a barn and find themselves in a magical world where the balance of language and numbers has become unhinged. Ivan and Daphne are set on a mission to find Lexicon's lost children who have been lured away by dancing lights in the sky. Along the way the survive a plague of punctuation, the fog of forgetting, feuding parts of speech, a panel of poets and illogical ...more

I won this book from First Reads. I'm looking forward to a quick read through now that it's arrived. I intend to give a preliminary rating after this. Then I'll give the book to my nephew and give his feedback later.

After reading a little, I can't judge the story fairly yet(so far, so good) but I do think the illustrations are lovely.

3.5 Stars for me. I'll add more detail later but a short assessment is: good story, beautiful drawings, suitable for tweens(and older) with good math skills, an e
"Lost in Lexicon" is a great book! It is about the adventures of two cousins Daphne and Ivan. Aunt Adelaide gave them two clues that lead them to the world of Lexicon. There are four lands: Land of Night, Land of Morning, Land Beneath the Sea and Land of Winter. Daphne and Ivan traveled across these lands and helped each village with something by solving riddles. They helped with the plague of punctuation, fixed the tile machine, saved Sammy, passed the Chasm bridge. My favorite part is when the ...more
I loved this book … anything that encourages kids to unplug is great! The adventure and characters are fun, with plenty of metaphor and symbolism in place names, character traits, and places. The puzzles are just clever enough to make it fun, but in no way frustrating for someone who hasn’t had the subject in school (e.g., Algebra).

Pros: Fun characters - like a Pet Thesaurus (llama) - and two typical teenagers engage kids in this action-packed adventure.

I enjoyed this book but found it a bit confusing. Ivan and Daphne are teenage cousins spending the summer with their great-aunt. She sends the cousins on an adventure after they complain of being bored. This adventure sends them into Lexicon, where they solve word and math puzzles to help rescue lost children.

Nik's math department chair gave this to him as a good-bye present last year (the chair was leaving the school) so we had it lying around. The concept is clever and I did enjoy it although the end felt a little forced. As in, not the best literature ever but a fun read, particularly if you have a kid who doesn't see how math could ever be of use in real life (albeit, a fictional real life!)

I thought this book good. In this book there was A LOT of math. The main characters were Ivan and Daphne. They find a magic "number" land and help lots of people. I want to read the next book ice castle.

Inspired by The Phantom Tollbooth, but original enough to be different. Fun adventures, but too didactic in places. See my full review

When I first started this book, I was expecting something along the line of "The Phantom Tollbooth". It was similar but got more complicated, mathematical, and diabolical towards the end. I did enjoy it but think I still prefer "The Phantom Tollbooth".

I enjoyed the book. It is inthe same realm as phantom tollbooth with the imaginary worlds of language and math. It was a good adventure and I like the way sheincorpated both math and language concepts into the story.

The plot was clever and moved quickly. I loved that the adventure moved forward through math and English, but it never seemed too forced. My 11-year-old and 7-year-old both loved it as a read-aloud; they grasped what they could and let the rest go on by without any problem.

I liked this book a lot! I look forward to reading the next title in the series. I'm not sure why Goodreads has two editions that seem disconnected, so I'm putting my rating and comments on both. My 11 yr old liked it too.
I thought that it was an interesting concept, but I wish that there was more actual puzzles to figure out. I also though that it was a very easy read for some of the advanced concepts it talked about.

Very clever book! Fun to read, even as an adult. Loved that the characters had to use their wits to solve the mysteries, and that lots of different kinds of puzzles were involved.

Not as curriculum related as I had hoped, but good. I will probably look into having the author visit next school year.

I get an email excerpt from "Book Daily..." I read the excerpt from this one and though it would be a fun read for my granddaughter who is 10. The story sounds fun.

An absolutely delightful read and a must for any fan of The Phantom Tollbooth. Two cousins journey to lands of words and numbers and undertake a quest to rescue children missing from the lands.

Fun and clever premise, but I didn't finish it. To me it seemed like a YA book that really needed a YA audience.

Wonderful book for kids. Shhh. Don't tell them they're learning while being entertained.

I liked this. Emphasis in fantasy adventure on words and math. (I did think there would be more math...)
