This is book number 1 in the Crime Travelers series.
While sleeping on the roof of his father's hotel, thirteen-year-old Lucas Benes finds a baby alone and learns that the Good Company has restarted its profitable kidnapping business. Brainwashed (Crime Travelers #1) tracks the secret urban adventures of the New Resistance, a network of international teenage spies. Lucas leads a group of friends through the hotspots of Paris-from the catacombs to the Eiffel tower-in an all-out effort to sabotage a brainwashing ceremony that could potentially turn them all into "Good" kids. A squeaky-clean international thriller for kids. A reluctant reader's dream.
