Leonora Bolt. Deep Sea Calamity: Lucy Brandt

Leonora isn`t supposed to be building a submarine in a tree. Or turning the local wildlife luminous. In fact, she is supposed to be keeping her head down and drawing no attention - because Leonora Bolt is an inventor in secret.

But she can`t stop thinking of the clues she found to her missing parents` location. So, deep in hiding in Snorebury, desperately trying to avoid being discovered by her evil uncle, Leonora is hatching a plan.
