Landon Walker's To Do List: 1. Free his daughter from alien control. 2. Prove his ex-wife is not an eco-terrorist. 3. Keep the earth from becoming an alien battlefield. 4. Join the first manned mission to another star system. Nothing on the list can be checked off without visiting a secret shaman site in the mountains of Patagonia.
