The SEA is Ours is an anthology collection of steampunk stories by various South-East Asian authors, including names such as Olivia Ho, Marilag Angway, and Timothy Dimacali. I know very little about either steampunk or South-East Asian literature, so none of these names were familiar to me; however, a little online searching told me that at least some of them, such as Dimacali, were already well-known authors in the genre, and presumably were asked to contribute for that reason.
Were all of the contributors already established authors? In other words, is The SEA is Ours a collection of short stories by famous authors, the sort of anthology that might advertise itself by "includes stories from So-and-so!" - or is it a collaborative effort to create a new thing, a South-East Asian steampunk collection, by a mixed team qualified more by enthusiasm than experience?
