Fenestra Series by Amber Kizer

Sixteen-year-old Meridian has been surrounded by death ever since she can remember. As a child, insects, mice, and salamanders would burrow into her bedclothes and die. At her elementary school, she was blamed for a classmate’s tragic accident. And on her sixteenth birthday, a car crashes in front of her family home—and Meridian’s body explodes in pain.

Before she can fully recover, Meridian is told that she’s a danger to her family and hustled off to her great-aunt’s house in Revelation, Colorado. It’s there that she learns that she is a Fenestra—the half-angel, half-human link between the living and the dead. But Meridian and her sworn protector and love, Tens, face great danger from the Aternocti, a band of dark forces who capture vulnerable souls on the brink of death and cause chaos.

Meridian Sozu is a Fenestra—the half-human, half-angel link between the living and the dead. She has the dark responsibility of helping souls transition safely into the afterlife. If people die without the help of a Fenestra, their souls are left vulnerable to be stolen by the Aternocti, a dark band of forces who disrupt the balance of good and evil in the world and cause chaos.
Having recently lost her beloved Auntie—the woman who showed her what it meant to be a Fenestra—Meridian has hit the road with Tens, her love and sworn protector, in hopes of finding another Fenestra. Their search leads them to Indiana, where Juliet, a responsible and loving teenager, works tirelessly in the nursing home where she and several other foster kids are housed. Surrounded by death, Juliet struggles to make a loving home for the younger kids, and to protect them from the violent whims of their foster mother. But she is struggling against forces she can't understand . . . and even as she feels a pull toward the dying, their sickness seems to infect her, weighing her down. . . .
Will Meri and Tens find Juliet in time to save her from a life of misery and illness? And will Meri and Tens' own romance weather the storms of new discoveries?

Translation for my romanian readers:

Meridian, de 16 ani, a vazut in jurul ei doar moarte, de cand se stie.  Cand era copil, insecte, soricei, salamandre se  asezau in asternutul ei si mureau. In scoala primara a fost acuzata de tragicul accident al unui coleg. Iar la aniversarea de 16 ani, o masina se ciocneste in fata casei parintilor ei, si corpul lui Meridian explodeaza de durere. 
Inainte sa se recupereze complet, i se spune ca este un pericol pentru cei din jur si este trimisa la o matusa indepartata in Revelation, Colorado. Acolo afla ca este o Fenestra - fiinta jumatate om jumatate inger care face legatura intre vii si morti. Dar Meridian si cel care a jurat a-i fi protector si iubit, Tens, infrunta un mare pericol din partea celor numiti Aternocti, o formatiune de forte intunecate care captureaza suflete vulnerabile, in pragul mortii si cauzeaza haos.
