Narrative:

19 mins after takeoff, the captain called to inform me that we were going back to bos immediately and that we'd be on the ground in 10 mins. The gauge read 'zero' for oil quantity in engine #2. He said to prepare for landing as normal, but to be ready for an unplanned evacuate/evacuation if necessary. I then called the crew and told them all the information. We landed normally. Fire trucks escorted us to the gate without incident.
