Spy Songs — Susan L. Larmon

Erika thrills to German reunification firsthand, in 1990 Berlin; she suffers the consequences of the Gulf War raging in Iraq, and skirts Berlin anti-war demonstrations; she indulges in the Munich Oktoberfest, while on extended TDY in Hamburg; and she is caught up in time travel back to 1987, and foils spies spelling double trouble -- all amid a blossoming love affair between two friends. "Spy Songs" is Ms. Larmon's second book in her "Time Travel 101" series, following "Swan Songs."
