=== Clue Hunters ===
==== Amy Cahill ==== Amy Cahill (from Boston, Massachusetts) is a fourteen-year-old girl with jade eyes and red-brown hair.

Amy acquired a satellite, The Gideon, and linked it to a command center that linked Cahills across the globe. Amy took various lessons in self-defense and martial arts and began working out regularly. She attempted to reconnect with Ian Kabra but failed. She and Dan went on a small mission in Switzerland, where they encountered the Wyoming Twins and acquired Gideon's Ring. She had it made into a watch, which she wore. She then began dating Evan Tolliver.<ref name=":2" />
She and Dan were attacked on their school bus at 8:42 AM EST, then received a text from Vesper One. They immediately left, stealing various objects for him, such as the painting Medusa.<ref>{{Cite book |last=Korman |first=Gordon |title=The Medusa Plot |date=August 30, 2011}}</ref> In Shatterproof, Amy, believing Ian was the traitor, confronted him.<ref>{{Cite book |last=Smith |first=Roland |title=Shatterproof |date=September 4, 2012}}</ref> In Trust No One, she learned the truth about Sinead and confronted her.

During William McIntyre's funeral, Amy was attacked and thrown into an open grave. She escaped, discovering journalists and paparazzi were following her. The government seized the command center, while she and Dan went to confront J. Rutherford Pierce. She, Dan, and Nellie traveled to Ireland, where she discovered Olivia Cahill's journal and the antidote for the serum. With the help of allies, she led the Cahills to find various ingredients to the antidote. A fight with Jake Rosenbloom led her to journey to the Svalbard Global Seed Vault, where she almost froze to death but was saved by Cara Pierce. In Guatemala, Amy took a dose of the pure serum to save Dan. She began experiencing the negative side effects, giving Dan temporary power because she did not trust her judgment. In Cambodia, she was the most hesitant to trust Cara. At the clam bake, she flew the crop duster with the antidote, but lost consciousnesses and crashed the plane into the ocean. After arriving at Pierce Landing, Amy typed the passcode to shut off Pierce's nukes. She resigned as leader of the Cahills, giving power to Ian Kabra. She and Dan returned Olivia's journal, then took up traveling.<ref>{{Cite book |last=Watson |first=Jude |title=Nowhere to Run |date=2013}}</ref>
Following Nathaniel's takeover, Amy and Dan were recruited from Mont Blanc. Despite Ian being the leader, Amy was frequently looked to for leadership. She journeyed on the second Titanic, getting trapped in Antarctica by Alec Spasky. She was locked in a closet on an airship along with Dan and Hamilton Holt. Following the events in Mission Hurricane, Ian gave Amy her leadership position back. She traveled with Jonah Wizard and Hamilton Holt to Shanghai, where she was captured by Alec Spasky. He faked killing her, then allied with her. He brought her to The Hive, where she discovered Nathaniel's bees. Following Nathaniel's defeat, Amy decided Cahill leadership would transition to a new Cahill every four years. She appointed Dan the current leader.
She was willing to speak with Sinead and consider forgiving her and traveled with Dan to Havana. They found Sinead, escaping the city on a small motorboat and taking refuge at the abandoned Ekat stronghold in the Bermuda Triangle. There, Sinead brewed an antidote to the dancing virus, and Amy administered it to an infected Ian Kabra.

Along with Amy, he was attacked at 8:42 AM EST. In Rome, he found and stole an original copy of Il Milione, despite Atticus' pleas of letting it be sent to a museum for study. After explaining to the Rosenbloom brothers the Vesper's threats, the four become allies, traveling the world and stealing objects for Vesper One.<ref>{{Cite book |last=Korman |first=Gordon |title=The Medusa Plot |date=August 30, 2011}}</ref><ref>{{Cite book |last=Watson |first=Jude |title=A King's Ransom |date=December 6, 2011}}</ref><ref>{{Cite book |last=Lerangis |first=Peter |title=The Dead of Night |date=March 6, 2012}}</ref><ref>{{Cite book |last=Smith |first=Roland |title=Shatterproof |date=September 4, 2012}}</ref><ref name=":12">{{Cite book |last=Park |first=Linda Sue |title=Trust No One |date=December 4, 2012}}</ref><ref>{{Cite book |last=Baldacci |first=David |title=Day of Doom |date=March 5, 2013}}</ref> After witnessing Nellie getting shot, he secretly began collecting the 39 clues. In Trust No One, he met with Cahill scientists Sammy Mourad to make the serum. In Day of Doom, he tried to take the serum, but Amy confessed to switching it out with water. Unknown to her, he had a second dose, which he saved for later. Between Cahills vs Vespers and Unstoppable, J. Rutherford Pierce stole Sammy's lab research that existed because of Dan. In Countdown, when Dan was in danger of falling to his death, Amy took the serum to save him.
In Athens, Dan unintentionally broke two skydiving world records while escaping from Melinda Toth. He experienced firsthand the tidal wave intended to recreate Hurricane Katrina in Amsterdam. In Mission Atomic, he was captured by Nathaniel and brought to The Hive where he saw the killer bees. In Outbreak, he was adamantly against forgiving Sinead but agreed to venture to Havana with Amy. Once Dan had confirmation that Sinead's antidote worked, he injected himself with the virus to keep enemies away from the Cahills.

During the Clue Hunt, Nellie agrees to travel to Paris to help Amy and Dan, though is later convinced to continue traveling and accompanies the siblings throughout the hunt; as they have limited financial resources, she charges most airfare and lodging to her credit card. When Amy and Dan discover Madrigal messages on her phone and laptop, she initially lies and claims they're from friends, though is eventually forced to confess when helping the Madrigals initiate Amy and Dan into the secret branch.
Nellie is one of the seven Cahill hostages taken by Damian Vesper. Following the Cahill's failure to steal The Medusa, she is shot in the shoulder. She feels significant guilt in Phoenix's apparent death, having served as the hostage's unofficial leader for their time in captivity.
When Amy and Dan travel to Ireland to escape Pierce, Nellie investigates Sammy's suspected kidnapping and discovers Trilon Laboratories. Initially posing as a scientist under the alias Nadine Gormey, she eventually joins Sammy in captivity and serves as the staff's pastry chef.

Along with Sammy, Nellie travels to Singapore to investigate the Chen family in response to The Outcast's rise to power. She encounters a disgraced Sinead and is attacked by Alex.

His ''Philosophiæ Naturalis Principia Mathematica'' (Latin for "Mathematical Principles of Natural Philosophy"; usually called the ''Principia''), published in 1687, is one of the most important scientific books ever written. It lays the groundwork for most of classical mechanics. In this work, Newton described universal gravitation and the three laws of motion, which dominated the scientific view of the physical universe for the next three centuries. Newton showed that the motions of objects on Earth and of celestial bodies are governed by the same set of natural laws, by demonstrating the consistency between Kepler's laws of planetary motion and his theory of gravitation; thus removing the last doubts about heliocentrism and advancing the Scientific Revolution. *'''Edmond Halley''': {{post-nominals|country=GBR|FRS}} was an English astronomer, geophysicist, mathematician, meteorologist, and physicist who is best known for computing the orbit of the eponymous Halley's Comet.
