The Midnighters Trilogy is a science-fiction fantasy series written by Scott Westerfeld. It was published by Eos in 2004. It comprises three books; The Secret Hour, Touching Darkness and Blue Noon. Over the course of the trilogy Jessica encounters other Midnighters with whom she allies herself. The protagonists in the trilogy are the eponymous Midnighters Desdemona (referred to as Dess), Rex, Jonathan, and Melissa. The antagonists of the series are Darklings and Slithers, dangerous and powerful beings that created and live in the Blue Hour.
In the Midnighters Trilogy, individuals born at midnight are able to live within the Blue Time while in Bixby, Oklahoma. These individuals are referred to as "Midnighters". As well as the ability to travel within the Blue Time, each Midnighter is gifted with super-human abilities. It is implied in Blue Noon that a Midnighter's power will not work outside of Bixby, however this remains unconfirmed, as none of the Midnighters leave the town during the course of the trilogy. Alongside their superhuman abilities comes the disadvantage of being highly sensitive to intense light.
In The Secret Hour, it is revealed that prior to the current generation of Midnighters, there used to be a large collective of Midnighters who, for all intents and purposes, ran the small town of Bixby in an attempt to protect it from the Darklings. Rex manages to deduce this from both historical accounts and "The Lore", notes made by previous Midnighters. However approximately fifty years before the beginning of the book the lore ceased to be updated for unknown reasons. The disappearance of the previous generation of Midnighters remains a mystery until the second book Touching Darkness.
The Midnighters Trilogy features five main protagonists, all of whom are Midnighters. Despite all possessing the ability to pass into the Blue Time, they do not always work together - resulting from personal conflicts between members.
For the majority of The Secret Hour, Jessica's ability is unknown. At the conclusion of the novel, it is revealed that Jessica is a "flame bringer", a rare talent that allows her to create fire and use electrical devices during the Blue Time. This makes her a valuable addition to the team, as she can use this ability to be a formidable opponent against the darklings, who fear light, fire and technology. Her first use of this power was a flashlight initially named Serendipitous. As both fire and technology can be used outside the blue time, Jessica's power is effectively useless in regular-time. (However, she is the only one who does not suffer adverse effects from being in daylight; Rex is effectively blind, Dess becomes photophobic, Melissa is plagued by the thoughts of humanity, and Jonathan must constantly shift between low and normal gravity)
