Wild Twins, The

Identical twins Amber and Serena have crossed ferocious seas on a voyage from Hawaii to San Francisco in a small sailboat; climbed trees with howler monkeys in the Amazon; entered the worlds highest marathon; raced for 322 kilometres on a dogsled; scaled Mount Cook, New Zealands highest mountain; and survived in the African wilderness naked for 21 days. This book is about conquering fears, teamwork and never giving up.
