Billy Sure, kid inventor and CEO of Sure Things, Inc., discovers a big
secret about his mom in the sixth book of a hilarious middle grade
series!
Billy's mom has always claimed she is a scientist doing research for the
government, but he's always suspected that there was more to the story.
And as it turns out, he was right! His mom is a spy, and now she has
enrolled him in spy school so he can create inventions for her
top-secret spy unit.
Billy is thrilled, especially because he gets to try out all of the
awesome spy gadgets and meet three other super smart spy kids. But when
Billy is offered a chance to become a spy himself, he has a big decision
to make. Does he want to become the world's youngest spy...or is it
enough just to be Billy Sure, Kid Entrepreneur?
