Publisher's Summary

Eleven-year-old twins Oliver and Celia Navel live on floor 4-1/2 of the Explorers Club with their father, Dr. Navel. Their mother, Dr. Navel, has been missing for years. So when an explorer shows up with a clue as to where his wife could be, Dr. Navel drags Oliver and Celia to Tibet to find her.
Once there, the twins fall out of airplanes, encounter Yetis, travel through waterfalls, and end up in the Demon Fortress of the Warrior King where they - just possibly - might find their mother and save their father from the Poison Witches.
Thing is, they would much rather be watching television. And if their trip doesn't work out as planned, the twins could end up as slaves to Sir Edmund Thitheltorpe III, an evil explorer with breath that smells like boiled carrots and who has it in for the whole Navel family.

Great book!

My son is 11, and he really enjoyed listening to this AB, after reading the book. I highly recommend this AB.

Wonderful story

This book is filled with adventure and humor and is great for both girls and boys. My seven year olds loved it. I wish they had the other three books in this series on audible. It is great for a long car ride. We first read this book last year when the kids were 6. It is well written and enjoyable to parents as well.
