The Amazon Code (Harvey Bennett Thrillers Book 2)

Deep within the Amazon rainforest, a secret lurks. A secret that could change the world.
...A secret worth killing for.
When her company discovers a remarkable hidden message in the dreaming brains of her subjects, Dr. Amanda Meron unknowingly invites disaster unto her company. The clues seem to be pointing her to one of the remote places on the planet:
The Amazon Rainforest.
When Harvey "Ben" Bennett gets a hint that the nefarious organization he's been searching for has turned up in Brazil, he and his new girlfriend Juliette Richardson race to the jungle to discover what they're after — and hopefully stop them.
From the myth of the lost city of El Dorado to emerging science technology, The Amazon Code has it all: action-packed adventure, an exotic setting, and characters you'll fall in love with.
