The book starts with the furthering of the familiy trying to get in good with Damian's family. Yor knew the mother but Anya is really working on the son. It's not going well. Yuri visits and is still creepily obsessed with his sister.
Most of the book is based around a school trip that has gone terribly wrong when two of the buses are waylaid by dissidents. Anya and Damian are able to work together to get everyone home safely.
