4.5 stars! 
 Onyx was pretty Good! ... I Really Liked It :) 
 After being healed, katy has changed... the healing has changed her... she became something else and she struggled with the differences. Her struggling with the change was very well characterized and felt very real. 
 And.. Daemon is still the same Smartass that drives katy nuts... but he also starts being Sweet and Protective of her ... I so loved him 
 There were lots of Feels and the relationship between Daemon and Katy was great ... I loved seeing their love grow and Katy comimg to terms and accepting her feelings for Daemon. 
 And... There's still the Powers and the constant Danger... with the Arum and the DOD around... 
 and There were TWISTS... Not all is what it seems like... 
 so... this one was a Very Entertaining, Interesting Read ... it kept me hooked and has left me wanting to read the next book - Opal
