Lena looks forward to receiving the government-mandated cure that prevents the delirium of love and leads to a safe, predictable, and happy life, until right before her eighteenth birthday and her treatment, when she falls in love.

After falling in love, Lena and Alex flee their oppressive society where love is outlawed and everyone must receive "the cure"--An operation that makes them immune to the delirium of love--but Lena alone manages to find her way to a community of resistance fighters, and although she is bereft without the boy she loves, her struggles seem to be leading her toward a new love.

Accompanied by an eccentric, human-sized rat, Liza embarks on a perilous quest through an underground realm to save her brother, Patrick, whose soul has been stolen by the evilest of creatures--the spider-like spindlers.

After one fateful night, Sam wakes up with no future at all. Trapped reliving the same day over and over, she begins to question just how perfect her life really was. And as she begins to untangle the mystery of a life suddenly derailed, she must also unwind the secrets of the people closest to her, and discover the power of a single day to make a difference, before she runs out of time for good.
