Savage Bonds

Almost to DNF this one, but I really want to pull through and finish the series. But f#@* I can't stand Oli crying and self loathing any more, and the fact that we don't know what she is hiding, and why, and all these, is getting very tiring. I mean, all of them have proven not to care of what her power is, so why is she so much still trying to hide things and doesn't sit to explain.
The plot holes are getting bigger and I am so damn pissed, because this series had all the potential of becoming something great. The idea is so perfect, but the storyline is lacking.
Also, when of her bonds loses a very important person, I want to smash her head on the wall for thinking only herself, how much she misses her parents and that he doesn't treat her good... she is a selfish person and I will not change my mind.
