This fascinating read has compelling characters, solid worldbuilding and
frenetic action. Mikhail and his foster brother are gripping protagonists, and the quandaries they negotiate are just as interesting as their more physical interactions. Fans of Spencer's Tinker series will find much to like.

When the Fenrir's warp drive appears at Plymouth Station, Captain Mikhail Volkov is put in charge of figuring out where it came from -- because the Fenrir was lost in a jump drive accident. When Mikhail and crew jump to the coordinates, they find themselves in the pocket universe Sargasso, where humans and aliens live together. What Mikhail also finds there will test the limits of his sanity and perhaps help him find a way to end the war between humanity and the aliens. (Baen, Dec., 400 pp., $25.00)
