The Shifter's Stolen Fae

The main character was good until the end when after when a small betrayal suddenly makes her shift toward the man that abused her and nearly killed one of her friends. Seems just like a cheap way to go exploring the other side of the conflict at the expense of character and really made me disengage from her entirely. It didn't really make sense. Even if she was mad and ran for it why would she think about going back to Malcom?

The iron fighting cage is also not consistent. At the start we see a shifter turn into a tiger and fight a troll. At the end another shifter turns into a wolf and enters and then is killed by the cage. So does it count after the shift is complete or not? Was the magic messed with before hand? Or was it an convenient way to kill a traitor by the author?

There where some decent things going on plot wise but the writing failed to convey tension...or really much emotion at all for me.
