If you're little, your older brother might not take you along. If you're always lost, you'll be reminded of it and constantly disciplined. Sometimes you just want to forget all that and imagine yourself as Superman. Or at least Superboy. But even Superboy can get lost...
This book is from an autobiographical series about a boy named Ulf. Ulf is one of Stark's most colorful characters; he wanders from book to book with his mischievous older brother and grumpy grandfather.
