Reagan Terri Holt is a member of the Holt family. She is the daughter of Eisenhower Holt and Mary-Todd Holt, twin sister of Madison Holt and younger sister of Hamilton Holt. She is 11 like Dan in the first series and later becomes 13 in the second series.
Apparently she wants to be a ballerina but is afraid to tell her siblings because "they won't stop laughing for a zillion years". She is part of the Tomas branch. She is very strong (like all Holts) and also loves to exercise. She also was apprehensive about doing things to hurt competitors early in the clue hunt, like burying Dan and Amy. Like her brother Hamilton, she often shows a softer side.

Appearance and Personality Edit
Reagan Holt is one of the Holt twins, and is shown to be the kindest out of her siblings and parents. Like the rest of her family, she is shown to be athletic and muscular, despite her being only 13. She is a brunette, unlike her twin, who is blonde. She is also described as having a crooked smile like her sister. Reagan and her brother and sister commonly wrestle throughout the series, or are described slugging each other. She wears a purple running suit both during the Clue Hunt and at Grace Cahill's funeral.
Reagan is athletic, involved in various sports, and tends to be overly aggressive towards her peers. At the same time, however, she is not as ruthless as her family, as her brother and sister often tease her about 'going soft.' She also has an affinity for ballet. She is the smartest and the most intelligent one in her family after Hamilton. In the first book, she is the only one to protest against leaving the Cahills in the empty grave in Paris, France. She can be very mean but also very nice and very fair.
As Reagan is a Tomas, she has the basic skills of one:
- Enhanced strength.
- Enhanced running.
- Enhanced agility.
- Enhanced physical edurance, etc.
The Maze of Bones Edit
Reagan is introduced at Grace's funeral when she and Madison hold Dan upside down and then drop him on his head. She and her family are invited to Grace's will reading, and when Mr. McIntyre informs the Cahills about their ancestors, she suggests Lewis and Clark as a likely Cahill. The Holts join the Clue Hunt, and Reagan and her siblings are shown fighting over ice cream in an ice cream truck in Paris. Reagan aids her family in monitoring the Lucian Base. Her siblings make fun of her for going soft.
At the graveyard in Paris, shortly after, she tries to convince her family to help the Cahills out of the grave trap prepared by the Lucians. She helps protect the Cahills from the Lucians before being knocked unconscious by Dan's concussive grenade. She hates Lucians.
One False Note Edit

The Medusa Plot Edit
Reagan is first shown swimming in Puerto Rico, training for the Ironman trialthlon world championships, when she spots a shark in the water. She sees a shark-proof cage attached to a boat with a scuba diver in it and swims towards the cage, getting in just in time. When she gets onto the boat, she tries to thank the people who rescued her, but sees a gun pointed to her head. The people on the boat turn out to be Vespers, who take her hostage.
In an attempt to break out, Reagan is seen to have fallen while doing pushups. When the rest of the hostages check on her, it is shown that she had "died", and the hostages grieve for her. When the Vespers come to take her out, she acts and takes down one of the Vespers. With a stolen gun, she helps her comrades escape, but stays back with Nellie to hold the Vespers back long enough for the hostages to get away. The hostages end up being recaptured and transported to another facility, with the absence of Phoenix.
Day of Doom Edit
She is escorted to the Rockies by the Vespers. She later escaped the Vespers and alongside the other hostages, Jonah, Evan, Ian, Phoenix, Amy, Dan, Jake and Atticus, destroys the Machina Fini Mundi. She appears at the end of the book practicing martial arts with Hamilton Holt.
