Exciting, vivid and enthralling - this will take the reader on a journey involving betrayal, twisted loyalties, magic and the powerful ties of friendship.

Alice Wyndham has been plagued by visions of birds her whole life, and only her best friend Jen understands her terror. So when an accident leaves Jen in a coma, Alice is devastated. Then the mysterious Crowley reveals that Alice is an aviarist: capable of seeing nightjars, magical birds that guard human souls. And Jen’s nightjar has already flown to Death’s aviary, the Black Menagerie. Unless Jen and her soul bird can be reunited, she won’t recover – and only Alice can save her.

With Crowley’s help, Alice travels to the Rookery, a hidden city within the London she knows. Here, surrounded by others with unique powers, she begins to hone her own newfound talents.

However, she’s being hunted by a faction intent on annihilating magic users. And is Crowley really working with her, or against her?

Alice must risk everything she holds dear to save her best friend – and uncover the strange truth about herself.
