Build the machine! Save the family!

When 12-year-old billionaire Zig Zephyr discovers these words in his dead grandfather’s journal, he has no idea what they mean. But he quickly learns that Alton Zephyr—famous inventor, jewel thief, escaped prisoner—had many secrets…beginning with the lab hidden under his family’s garden. And his plans for a time machine. 

With the help of an eccentric scientist and his two children, Zig and his friends soon embark on a chase through history, solving a series of riddles Alton left hidden in time. Along the way, they experience some of the most important moments in American history—and learn that old family mysteries sometimes come back to life and danger is just seconds away.

Reader Reviews

“As a homeschool mom for the last 16 years, I have read my share of middle grade books to children and have been bored to tears by some. Not this one, it’s page turner full of surprises. The author also does a great job mixing in just enough rich vocabulary to expand your child’s, mind but not so much that they would get lost, frustrated, or confused causing them to put the book down.

I genuinely love books with historical references because history is fascinating, but kids don’t always think it is. The author wrote an exciting story referencing many historical events in a way that’s interesting to kids. As a mom, I loved that history was brought up in a way that drove us to google some of the times and places to find out more.

I thought I had this book figured out, but I was wrong. At one point I literally gasped out loud.”
