This science-history nonfiction adventure mash-up will be on every middle grade reader's radar.

Who knew that an improbable rescue during WWII would be facilitated by scientific discoveries in the 18th century?

Expert researcher and educator Jeff Lantos makes the history-science connection between batteries and radar and one oceanic adventure in this engaging middle-grade escapade told in two intertwining storylines.

Readers are first invited to follow scientific discoveries in the 1700s that eventually lead to the creation of radar, and are then immersed in a world where World War II rages. German U-boats sink ships, and the ship just hit has an American mom and her two young kids aboard. Now Ethel, Robert, and Mary Bell are on a raft with fourteen other people, floating in the ocean and hoping for rescue.

Lantos expertly weaves radar's story of discovery with the Bell family's harrowing journey, bringing readers on an exciting fast-paced adventure through history.
