Darkness Before Dawn de J.A. London

           Only sunlight can save us.

We built the wall to keep them out, to keep us safe. But it also makes us prisoners, trapped in what’s left of our ravaged city, fearing nightfall.
After the death of my parents, it’s up to me–as the newest delegate for humanity–to bargain with our vampire overlord. I thought I was ready. I thought I knew everything there was to know about the monsters. Then again, nothing could have prepared me for Lord Valentine . . . or his son. Maybe not all vampires are killers. Maybe it’s safe to let one in.
Only one thing is certain: Even the wall is not enough. A war is coming and we cannot hide forever.

 Romanian translation:  Numai lumina soarelui ne poate salva.Am construit zidul ca sa ii tinem departe. Dar zidul ne face proprii  prizonieri, prinsi in ceea ce a mai ramas din orasul nostru, ferindu-ne de caderea noptii.Dupa moartea parintilor mei, depinde de mine ca nou delegat al umanitatii- sa fac un targ cu lordul vampir.Credeam ca sunt pregatita, credeam ca stiu tot ce trebuie sa stiu despre monstrii. Nimic nu ma putea pregati pentru lordul Valentine sau cu fiul. Poate nu toti vampirii sunt criminali. Poate este bine sa las pe cineva inauntru. Un singur lucru es cert: zidul nu este de ajuns, un razboi este pe cale sa inceapa si nu ne putem ascunde pentru totdeauna.
