''Hider, Seeker, Secret Keeper'' is the second volume in a series and while I didn't feel I was missing anything, I shall certainly be buying the first.
Personally I felt much of the same pleasure reading this novel as I did when I read Philip Kerr's [[The Winter Horses by Philip Kerr|The Winter Horses]] which is also set in Russia, though in an earlier historical period. That too will appeal equally to the adult and the teen reader. For younger readers who love ballet there's [[Ballet Stories by Margaret Greaves and Lisa Kopper
.]] For adults Lucy Moore's recent biography of [[Nijinsky by Lucy Moore|Nijinsky]] comes highly recommended.
