Devoted is the sequel to New York Times-bestselling novel Elixir by American entertainer Hilary Duff with Elise Allen.

In an interview with MTV, Duff stated that "Devoted picks up basically where Elixir left off, and Clea has a lot of big questions to answer and decisions to make.

Through a series of flashbacks, it is revealed that the ghostly family all consumed the Elixir of Life over 2,000 years ago and have been living in immortality ever since.

They've trained their minds to gain psychic powers such as telekinesis and astral projection, but the Elixir is running out and soon they'll be left in a comatose state.

Clea reaches Sage just in time to witness his throat being cut and his blood turning to Elixir in a bowl.

Duff announced in July 2012 that the sequel and final novel in the Elixir series would be titled True and was released on April 16, 2013, by Simon & Schuster.
