Eternal Ones Series by Kirsten Miller

Haven Moore can’t control her visions of a past with a boy called Ethan, and a life in New York that ended in fiery tragedy. In our present, she designs beautiful dresses for her classmates with her best friend Beau. Dressmaking keeps her sane, since she lives with her widowed and heartbroken mother in her tyrannical grandmother’s house in Snope City, a tiny town in Tennessee. Then an impossible group of coincidences conspire to force her to flee to New York, to discover who she is, and who she was. In New York, Haven meets Iain Morrow and is swept into an epic love affair that feels both deeply fated and terribly dangerous. Iain is suspected of murdering a rock star and Haven wonders, could he have murdered her in a past life? She visits the Ouroboros Society and discovers a murky world of reincarnation that stretches across millennia. Haven must discover the secrets hidden in her past lives, and loves¸ before all is lost and the cycle begins again.

Haven Moore and Iain Morrow have been living a blissful life in Rome, an ocean way from the Ouroboros Society and its diabolical leader. But paradise is not to last. The mysterious disappearance of Haven's best friend, Beau, sends the pair running back to New York, where they encounter the Horae, an underground group of women who have spent centuries scheming to destroy Ad...moreHaven Moore and Iain Morrow have been living a blissful life in Rome, an ocean way from the Ouroboros Society and its diabolical leader. But paradise is not to last. The mysterious disappearance of Haven's best friend, Beau, sends the pair running back to New York, where they encounter the Horae, an underground group of women who have spent centuries scheming to destroy Adam Rosier. Only they can help Haven uncover the secret to Beau's whereabouts in one of her past lives. But their help comes at a price: Haven must infiltrate the Ouroboros Society, charm Adam Rosier, and lure him into a trap. It's a plan the Horae believe will save the world-but Haven and Iain fear that it may destroy the happiness they've been chasing for two thousand years.

Translation for my romanian readers: 

Haven Moore nu-si poate controla viziunile despre un trecut petrecut cu un baiat numit Ethan si o viata in New York care s-a sfarsit cu o tragedie inflacarata. In prezent, ea creeaza rochii deosebite pentru colegele ei de clasa, impreuna cu prietena ei cea mai buna, Beau. Designul vestimentar o ajuta sa-si pastreze echilibrul, cand traieste cu indurerata ei mama, ramasa vaduva, in casa tiranicii bunici din Snope City, un orasel minuscul din Tennessee. Apoi un grup de coincidente imposibile conspira pentru a o forta sa zboare la New York, ca sa descopere cine e si cine a fost.
In New York, Haven il cunoaste pe Iain Morrow si este atrasa intr-o relatie amoroasa de neuitat care pare a le fi pe deplin destinata si teribil de periculoasa in acelasi timp. Iain este suspectat pentru uciderea unui star rock, iar Haven se intreaba daca nu cumva el a ucis-o si pe ea intr-o viata anterioara. Vizitand Societatea Oroboros, ea descopera o lume intunecata a reincarnarii, care se intinde de-a lungul mileniului. Haven trebuie sa afle secretele ascunse in vietile si iubirile ei anterioare, inainte ca totul sa fie pierdut si ciclui sa reinceapa.
