The novel based on the upcoming Hollywood blockbuster by cult director Guillermo del Toro. A secret U.S. military lab in 1963: In the highly secure lab section F-1, a creature from the Amazon is being held captive, whose study is supposed to provide a breakthrough in the arms race. But one night, the cleaner Elisa discovers the being, which is half man and half amphibian. Elisa does something no scientist has thought of: she teaches the water creature sign language. When she learns that the "project" is soon to end up on the dissection table, Elisa knows she must save her friend - from a sealed-off lab, a sadistic general breathing down her neck, and Russian spies. New mystery-thriller excitement for all fans of "Hellboy" or "Pan's Labyrinth.".
