Scumble [EPUB ebook] 

On the day of his birthday, Ledger Kale thinks his normal life will never be the same again. Now he’s thirteen, his savvy has arrived; an extra-special talent that means everything has just fallen apart. If not everything, then certainly the television, the lawnmower, the plumbing in the kitchen, and the family minivan. He’s just become a one-kid demolitions expert – whether he likes it or not. Ledger now faces an extraordinary summer of adventure, as he learns if he can scumble his savvy, and put his world back together at the same time.
