3.5 stars 
 The surprise reveal or I should say 'twist' in the end of this was so unbelievably cheesy and contrived. (view spoiler)[ So all 4 Theronai females found so far happen to be sisters sired by the same father who is from another planet. Yes Lexi and Helen are now magically sisters! -__- (hide spoiler)] Did Butcher really need to go there? I found it annoying, highly unrealistic and IMO unnecessary.
