Hi, Trying to find a book where two girls go to a wax museum where all the sculptures seem to be in pain. They meet the sculptor who invites them to stay with him. Once there one of the girls poses for him and afterwards becomes sickly until she disappears. The sculptor attempts to convince the other to pose for him but she declines and tries to escape. She finds a secret passage that leads to a cavern full of flawed wax sculptures of the same woman. Eventually she learns that the woman is the maid who looks old but who is only 18 (somehow the sculptures aged her). In the end the maid helps her escape but the maid and the sculptor die when the place burns down. The main girl is badly burnt and half her face is scarred so she moulds herself half a face with some wax that ends up in her hand.

Other info: Set in early/mid 1900s I think its part of a series (Fyre) Pretty sure the wax ends up in her hand because she ripped it off the face of the guy she trusted who ended up being the sculptor in disguise Remember the dinner scene - the roses were red at the tips and white at the stem, something about the "life being drained out of them" Also at the dinner scene her steak was rare
