Everybody who looks at the Great Lakes knows they’re big, but why are they so Great? This book explores just that question. From sea serpents to sunken ships, from lonely lighthouses to fish on Prozac, Great Lakes: Fact or Fake? engages the reader in a quest to discover what’s truly beneath the surface and features evocative illustrations by Heather Lee Shaw that bring the subject to life.
