Aurora's End

Squad 312 has just lost a disastrous battle at Terra, and the team is now scattered across time as well as space. Some of its members are thrown forward into a bleak future, while others are flung centuries into the past. Each group has to work out how to stop the Ra'haam, and how to get back to their own timeline before the chance is gone.

This is the third and final book in the Aurora Cycle, a science fiction series about a band of misfits who may be the last hope the galaxy has. It picks up directly from the cliffhanger of the previous book, so it is not a place to start. Readers new to the series should begin earlier.

The plot rests on time travel, and it is genuinely complex. With the squad split across eras, the story follows separate threads that have to be tracked against one another. Expect fast, high-stakes action with a streak of humor running through it.

The book also carries romance and sacrifice, and it closes the series with an ending that has to be earned. It reads as a conclusion, with the whole cycle building toward one last push.
