Loot: How to Steal a Fortune by Jude Watson

Adventurous, mysterious, and full of comedy!  I highly recommend this book.  Kids who are cunning, smart people try to steal seven "magical" moonstones that decide a twin's fate.  Very good book!

The Outcasts (Brotherband Chronicles #1) by John Flanagan
