Sharks of Lake Erie

Sharks in Lake Erie

by H. John Hildebrandt

Sharks in Lake Erie has it all: Lake Erie. Bull Sharks. Nazi Gold. Roller Coasters. Secret Caves. Billionaires. Hot Summer nights.

While bull sharks (equally at home in salt and fresh water) suddenly appear in western Lake Erie, museum director Susan Massimino helps her police chief cousin investigate the brutal murder of a local farmer. Could an international terrorist group, headed by the grandson of a German general and funded by secret Nazi gold, be behind both events?

John Hildebrandt’s daring and original new novel about the lake he loves answers the question.
