Description:
In The Girl in the Tower, Vasilisa faces an impossible choice. Driven from her home by frightened villagers, she has only two options left: marriage or the convent. She cannot bring herself to accept either fate and instead chooses adventure, dressing herself as a boy and setting off astride her magnificent stallion Solovey.
  
But after she prevails in a skirmish with bandits, everything changes. The Grand Prince of Moscow anoints her a hero for her exploits, and she is reunited with her beloved sister and brother, who are now part of the Grand Prince's inner circle. She dares not reveal to the court that she is a girl, for if her deception were discovered it would have terrible consequences for herself and her family. Before she can untangle herself from Moscow's intrigues—and as Frost provides counsel that may or may not be trustworthy—she will also confront an even graver threat lying in wait for all of Moscow itself.
