Beautiful Dead book 1 of 4, completed series

Not alive. Not dead. Somewhere in between lie the Beautiful Dead.

Something strange is happening in Ellerton High. Jonas, Arizona, Summer, Phoenix. All dead within a year. 

Jonas Jonson is the first to die, in a motorcycle accident. But there are many unanswered questions, and the three deaths that follow are equally mysterious.  

Grief-stricken Darina can't escape her heartache or visions of her dead boyfriend, Phoenix, and the others who died. And all the while, the sound of beating wings echoes inside her head. 

Are the visions real? Or do the Beautiful Dead only exist in Darina's traumatized imagination?
