Tyra Bold is not what Kitty Strange and her team were expecting. She's an alien, but nothing like any of the aliens they've met before. And she needs help to find her missing friends and relatives. So it's a quick jump to Pansauria and take it from there. But things are complicated. Their search takes them to Lunaria, a dangerous sister planet to Pansauria; and then to Gaea, Concordia, and Aphrodisia, following up leads on Rosabella Rook and her mischievous daughter Regan.
