Puck, expelled from boarding school on Earth, is on her way to stay with her parents on the planet Shoon. On board the spaceship she befriends Hush, a native Shoowa who is also returning home in shame. He is desperately seeking a stolen treasure that was entrusted to him, a symbol of freedom for his people.
Puck and Hush must find the precious Soo before they reach Shoon. But who can they trust? And how will they save their own skins as they hurtle through space on a ship haunted by terrifying ghosts?
This book is a nice SF mystery blend. An easy, fast read since it's a YA book, but not a simplistic mystery, which is nice. Although I was able to predict one of the big twists at the end (it might have been telegraphed a little too much!) the larger mystery remained a mystery for me until the reveal to the heroine. There was some nice exploration of friendship and prejudice, and the heroine was wonderfully adventurous and as self-reliant as a youngster could realistically be. If you like SF mysteries, you should give it a try.
