There's a lot of setup in this issue for future developments. Rather than try to post excerpts from that, I decided to post the last nine pages, in which Boronwë's ship is attacked by slaver pirates.

The first 19 pages in brief: Boronwë is going off on a ship with a bunch of other cadets to their first post-graduation assignment, at the Sisterhood's fortress between the twin cities of Orange and Phyrus. The Queen of the Sisterhood sends two of her chief officers on the same ship, to secure renewal of the Sisterhood's treaty with them. The future of the treaty is somewhat in doubt as Andras, the leader of the slave traders of Giaour, has been bribing O'mah, prince of Orange.
( but enough of that, on to the pirate battle! )Christy Marx
has a website page devoted to Sisterhood of Steel; she has (I assume signed) copies of all issues available for sale, as well as posters and prints.
