Slow Train To Arcturus

The planet Miran had sent a spaceship to rendezvous with the enormous vessel that was approaching their star system. The vessel's design was odd - a multitude of separate globular habitats in a framework - and most of the alien team that entered one of the habitats were slaughtered by savage creatures called "humans." One alien had barely managed to escape to another habitat where the humans were more friendly, if rather technologically backward.

Eric Flint is a popular star of SF and fantasy. His 1632, which launched the New York Times best-selling Ring of Fire series, sold out in hardcover almost immediately, followed by multiple printings in paperback. His first novel for Baen, Mother of Demons, was picked by SF Chronicle as a best novel of the year. He currently resides in northwest Indiana with his wife Lucille.
Dave Freer, author of The Forlorn and the critically acclaimed A Mankind Witch and of many articles in  scientific journals, is an expert on sharks and an accomplished rock climber, a wine-taster, a chef  and was an unwilling conscript in the “undeclared” South African-Angolan War. With Eric Flint he has co-authored Rats, Bats & Vats, The Rats, the Bats & the Ugly, Pyramid Power and Pyramid Scheme.  He has also collaborated with Mercedes Lackey and Eric Flint in a sweeping alternate history-fantasy set in the Renaissance. The first two books in the series, The Shadow of the Lion and This Rough Magic have been enthusiastically received by critics and readers. The trio have also produced a sequel to James H Schmitz’s classic The Witches of Karres, The Wizard of Karres. Freer lives in KwaZulu, with his wife Barbara, two sons, and far too many dogs and cats.
