Epona, at the crucial moment.
To finish reading ...Corvallis.
To continue reading Stirling's Change series.
To reread Anderson's "Memory."
Maybe to check out John C. Wright's The Golden Age.
This last work is relevant because:
I have been told that it was written partly as a homage to Poul Anderson - and even to Harvest Of Stars (?) although I cannot track down where I read this;
it is set in a high tech utopian future and sf authors need to speculate more about this range of possibilities;
its author later converted to Catholicism.
Anderson and Stirling present sympathetic treatments of Catholics. We are able not only to accept supernatural beings as a premise in works of fantasy, and in Milton's Paradise Lost, but also to converse with contemporaries who conceptually inhabit a universe where such beings do exist, like CS Lewis and John C. Wright. We encounter the infinite in philosophy and art.
