Arielle Immortal Quickening (The Immortal Rapture Series) (Volume 4)

A fatal night... 
College co-ed Arielle Lloyd is on vacation with her immortal love, Sebastian Gaulle, when they receive word of a dreadful accident. Her dear friend Gabrielle hovers near death. But it's much worse for her beloved friends, Eva and Ian. In spite of Eva's magical abilities, their lives are cut tragically short. 

An immortal choice... 
Troy Vasser's only love is Gabrielle, but on the night of the accident, his deepest concern is for their dying friends. When the life force within Ian and Eva flickered dangerously low, Troy was forced to make a hard choice. He could either let them die, or take away their humanity and force them to live again as immortals. He did the only thing he could. Now it is up to Arielle to handle the fall out.

A quest for vengeance... 
Danger continues to stalk Arielle's life. Unbeknownst to Arielle, her new professor is an immortal, and he is furious when he discovers that Arielle is wearing an amulet that should only be owned by immortals. Sebastian's nemesis, Annabel, is still pursuing her quest to destroy Arielle. But what Annabel doesn't realize is that Arielle's circle of friends has drastically changed. There are new immortals that adore her and have vowed to protect her.
