Daisy May Johnson's How to Be Brave is a delightfully zany yet heartwarming middle-grade novel about a young girl who bands together with her boarding school friends to find her missing mother.

Calla North and her mother Elizabeth live a quiet but happy life together. Elizabeth happens to be the world's leading expert on ducks-but unfortunately, being an expert on ducks doesn't always pay the bills (no pun intended).

When Elizabeth is offered a well-paid research trip to the Amazon, it's an opportunity too good to miss. But while her mother's off exploring, Calla winds up at boarding school. No adventures are likely to find her there-or so she thinks.

Then Calla receives the terrible news that her mother's plane has gone missing. Can Calla, her friends, and a motley crew of nuns defeat an evil new headmistress and find Elizabeth before it's too late?
