The Big Sting, by Rachelle Delaney

Leo's Dad, currently between jobs, has discovered a personality test that he believes can correctly identify your key behavioral traits.  He tests it out on the family and Leo's little sister Lizzie is an "adventurer," which makes sense because she is always getting into trouble without a second thought.  Leo comes up as an "auditor" which reflects his cautious nature and non-adventurous personality.  It frequently falls on him to keep Lizzie out of trouble.

These personality traits get tested when the family goes to visit grandpa on a remote island off of the coast of British Columbia.  One night grandma's beehives are stolen and the kids and their grandfather launch a search to find them.  While Leo is reluctant to do something as risky as to try hunting down potentially dangerous bee thieves, he rises to the occasion, proving that labels aren't everything.

Pleasant and lively middle reader.  The life lessons are largely in second place to a riotous cast of quirky supporting characters and some low-key adventuring.  While the kids fall into some dangerous situations, there's nothing too scary and Leo largely saves the day.  Sadly, there's not not very much on bees themselves.
