Breakaway (Star Trek Next Generation: Starfleet Academy #12) by Bobbi J.G. Weiss, David Cody Weiss

Before she was an officer aboard the "U.S.S. Enterprise."

No one ever said Starfleet Academy would be easy, but Cadet Deanna Troi never expected it to be this hard, either. She's been taken prisoner by pirates on the "Borocco-Kai," and now she's weaponless and helpless.

Of course, its only a test: a holodeck exam all freshmen must pass. But for Deanna, the stakes are even higher than usual. She's opted to take the test early because it seemed like the only way to save her future at the Academy.
