The Wood Queen - Karen Mahoney

Born into the mysterious world of an ancient alchemical order, Donna has
always been aware of the dark feud that exists between the alchemists
and the fey. Her own mother - bound by a dark Faerie curse - has been
confined to a hospital bed for as long as she can remember . . . But now
there is a chance to release her, and Donna will stop at nothing until
she is free.

Armed with her own brand of powerful magic, Donna
must face the fearsome Wood Queen in order to save her mother. But in
the Ironwood - a place that haunts Donna's dreams - there is far greater
and more dangerous magic already at work . . .
