Book Querie

[Seusse]

I hope someone can shed a light on this for me, it was a book i read years ago about a maze/labarinth i think it was evil or something i dont think anyone had ever made it thro, theres also something about keys for gates i think, and if i remember right a female manages to conquer it, its not the bowie labrinth and its not the Kate Mosse one either any help would be appreciated thanx in advance
