Blood heir, by Ilona Andrews

From the book Blood heir. It's about Julie and Derek, but there are some appearances of HUGH... And these appearance, well, are the BEST PART of the book, so if you are a Hugh fan go grab it!

It didn’t matter how powerful you were. Life always found ways to stab you and twist the knife in the wound. Nobody was immune.

I kept my emotions divorced from my actions. I hid my weaknesses. Even when anger crested in me in a hot, red wave, I surfed it to my goal. I never lost my hold in front of other people unless they were family. If I screamed, it was calculated. If I wept, I did it for impact. Derek made me lose it. I kept going over our conversation in my head. It was the way he had looked at me. The way he sat, the way he smiled, the way he spoke. Everything he did reminded me of what I’d left behind. Somehow, he bypassed my armor and got an honest, instinctual response out of me. I hated that so much.
