Expendable

Expendable is a science fiction novel by the Canadian author James Alan Gardner, published in 1997 by HarperCollins Publishers under its various imprints. It is the first book in a series involving the "League of Peoples", an assemblage of advanced species in the Milky Way galaxy. There is a "sub-series" involving just the character Festima Ramos, and sometimes the female Oar. The novel introduces many concepts in Gardner's "League of Peoples" universe, such as the Explorer Corps, Sentient Citizens, and the League itself.
