Here's the synopsis, direct from the publisher:

As tensions rise on the station, the science vessel Athene Donald arrives as part of its journey of exploration. The brainchild of Doctor Katherine Pulaski, this ship is crewed by different species from the Khitomer Accords and the Typhon Pact. Pulaski’s hope is that science will do what diplomacy has not: help the great powers put aside their hostilities and work together. But when the Athene Donald is summarily stopped in her voyage by the powerful vessel of a hitherto unknown species, Pulaski begins to wonder—will this first contact bring her crew together or tear them all apart?
