In the fourth book in Alyson Noel's Immortals series, "Dark Flame," Eve once again has to fight for her own survival, for her body, soul, and eternal love.

Eve tries to help Haven adapt to the world of immortals. However, the latter, overwhelmed by her new powers, begins to act irresponsibly and frivolously. Eve is worried that the secret of the immortals may be revealed to everyone. But her efforts to keep this secret only bring Haven closer to Roman and a gang of immortal villains.
At the same time, Eve, trying to extract the antidote from Roman, gets caught up in black magic. The spell begins to work against her and Eve becomes so tied to Roman that no amount of willpower can resist this destructive attraction. She can't get the villain out of her head, she craves his caresses. The more Eve tries to overcome this obsession, the weaker she becomes, and Roman only waits for a convenient opportunity... With every step, Eve gets closer to the edge of the abyss.
Unable to undo the spell, Eve turns to Jude for help, thereby endangering herself, Damon, and their love.
