About 10 years back, I read a series of books about an Australian adventurer (ex-military Special Forces type of guy).
- The protagonist has a metal arm (he loses the arm in the first book I think).
- He has a scientist/genius-type friend nicknamed Wizard who builds a metal arm for him
- In one of the books, the villain is his father (who is in the American military, very high ranking post).
- He also has a daughter (around 10 years old I think) who is a major part of the adventures.
- He is kind of Indiana Jones (who is mentioned by the protagonist in the book once or twice) as far as the type of adventures are concerned.
However, I don't remember the name of the protagonist or the author or any of the book titles. Thus, I am not able to find by searching any of these details on Google or something.
