Expedition in Time — Monique Martin

Simon and Elizabeth Cross are enjoying a romantic mission in 1936 Miami when things go south--literally--to Rio de Janeiro. The mysterious artifact they've been tasked to retrieve isn't sitting in some museum in Florida; it's buried in the Lost City of El Dorado hidden in the darkest jungles of Brazil.

As if trekking through a jungle where everything wants to kill you--including cannibals--wasn't dangerous enough, they also have to deal with a ruthless archaeologist who will stop at nothing to find the Lost City and a pair of Nazis hellbent on bringing the power and the glory of the artifact back to the Führer himself.

Unless Simon and Elizabeth can find El Dorado and the artifact first, history will be forever changed, and not for the better. 'Cause, ya know, Nazis.
