The Siren Series by Hannah West

Relentless memories plague Inara. People she’s never met. Places she’s never been. A fate that can’t be hers. Each memory feels real. So right. More so when she meets one of the hallucinations and discovers the nightmares are true. Riddles will place all Inara knows on a blade’s edge, and it will be left to her to tip the scales or let the darkness she never knew was lurking reign forever.
