Cauldron of Bitterness

Magic is a double-edged sword, and Siobhan knows the sting of its blade better than most.

Old scars have peeled open to spill out the horrors within, and Siobhan has learned to fear her shadow.

When the Red Guard comes to assess the Raven Queen as a threat, she must convince them she's worth more alive than dead. They want the truth behind her secrets, and she wants access to forbidden knowledge. Fortunately, she knows that sometimes the best defense is a dangerous reputation-even one built on deception.

But as Siobhan delves deeper into Myrddin's encrypted journals and the restricted archives of the Thaumaturgic University, she begins to understand why some knowledge is kept under lock and key. The secrets she uncovers whisper of magics that should not exist, of powers that should not be touched.

But knowledge, once gained, cannot be unknown.
