Stolen invention

Warning: This book will have you clutching your sides with laughter. An adventurous read and plenty of incredible inventions await!

Leonora’s room – a top-secret laboratory (No Entry!) – is at the very top of an old, abandoned lighthouse. The lighthouse stands on Crabby Island. And Crabby Island is right in the middle of… absolutely nowhere.
Leonora Bolt spends all her days in her laboratory creating the most amazing inventions under the watchful eye of her wicked Uncle Luther, who steals her inventions and passes them off as his own on the mainland. This includes her latest, most secret invention yet.
Can Leonora, with her new friend Jack and other helpers – an otter with special abilities, a questionable cook and a singing captain – outwit Uncle Luther and get her stolen invention back?
