Big Bad Ironclad!
By Nathan HaleBig Bad Ironclad! is part of the series called Hazardous Tales by Nathan Hale. This book is about the race between the North and the South during the US Civil War to build bigger and better ironclad warships. The North tries to sabotage the ships of the South, failing and instead indirectly helping them get ideas about how to improve their ships. The South first builds the Viriginia, a giant Ironclad, so the North builds the Monitor, which is smaller but faster.
