The book "The French Pilot" can be ordered here in the U.S. from AdventistBookCenter.com
If you enter the address on Google - type the Title of the book THE FRENCH PILOT in the "search our site" box and the info comes up....you can read a book review under "details" and order a paperback copy for $14.99.
I pulled up The Signs Publishing Company in Warburton, Victoria, Australia, too, and got a good over-view about the company from Wikipedia. The book can be ordered thru them but it is $24.95 - don't know if it is ahard copy.
Glad to be of help -- especially since you have a Madeline in the family.....oh, I loved the book and bought one for my sister.Are you a descendant of a Lamoureaux? Do you live in the U.S.
