To the Stars (Leinster)

As described in 1953 edition of Space Platform, Shasta planned to publish Leinster's 3-book "To the Stars Series" within their "Shasta Junior" line as Space Platform, Space Tug, and Space Shuttle. Shasta published the first two, featuring character "Joe Kenmore", but not the third book Space Shuttle. Four years later, in 1957, Avalon Books published Leinster's novel City on the Moon, which continued the story of Joe Kenmore in a plot that centered on sabotage of a "Shuttle". The Avalon publication does not reference Shasta's "To the Stars Series", but is presumably the planned third book under a different title.
