Hi there,  My book is in Spanish. The title in English is "Walking between two worlds. Seeking the truth". This is a product of a long research around a lot of topics; history, technology, aliens, etc..., questioning the reality in order to see outside of the world we know. This could be very useful for people who are starting to wake up, or at least are open to read logical arguments.
