Amy Cahill was born to Hope Cahill and Arthur Trent. When she was six or seven years old, her parents died in a fire created by Isabel Kabra. Amy and her brother Dan were soon placed in the care of their great-aunt Beatrice Cahill. They would often visit their grandmother Grace Cahill.
When Amy was fourteen-years-old, Grace died, and she and Dan were thrust into the hunt for the 39 Clues. They are told of their great heritage and the role that the Cahill family has played in history. They collect their first clue: Iron Solute, and start off on the hunt for the 39 Clues. In Book 2, Amy and Dan find another clue, connected to another one of their famous relatives Wolfgang Amadeus Mozart and distinctly to Nannerl, his sister. They find the clue Tungsten by playing a part of Mozart's music. The relationship between Amy and Ian Kabra develops greatly in The Sword Thief, Book 3. When Ian and his sister, Natalie, make an alliance with Amy and Dan, Ian develops a crush on Amy while trying to trick her into falling in love with him. However, the relationship ends in disaster when the Kabras betray the Cahills. Despite the betrayal, Ian's interest in Amy is continuous and grows. Amy and Dan visit Egypt, the grave of the pharaohs, the land of the Sphinx, and the home of their next clue in Book 4 In this book Amy and Dan run into more of their relatives and Amy tries to forgive herself for falling for Ian's lies. In Book 5, the Cahill siblings find out that their parents went to Russia and accidentally went there without Saladin or Nellie. They received help from a Lucian named NRR, a.k.a Nataliya, daughter of Grand Duchess/ Anastasia. They make a temporary alliance with the Holts and ask them to look for the Clue in Siberia. However, after finding the Clue (one gram of melted Amber), Eisenhower refuses to continue their alliance. The Cahill siblings, with Nellie and Saladin, are now on their own again. In "In Too Deep", they go to Australia and meet the cousin of their father, Shep Trent. Their time to spend time with Shep was short because Isabel Kabra enters the hunt and is on their track. Because of this, one person (Irina Spasky) sacrifices her life for Amy, Dan, and Alistair Oh and shocked them all. Next, in Book 7, they go to South Africa and find that there is a Tomas stronghold there. They mistake the clue for diamond but figures out it is Aloe later on in the book.They find Grace's plane, The Flying Lemur, and they are still being tailed by Isabel Kabra. In Book 8, Amy and Dan get separated for the very first time because of Dan getting angry at Amy for thinking their parents might be bad people. Because of this, Amy is now worried of what will happen to her brother. Eventually, they reconcile and go up Mount Everest to get the next clue. During "Storm Warning", Book 9, they finally learn what Madrigals and their true intentions are. They find out Nellie has been sneaking information to William McIntyre but finds out the truth in the end. They are also granted full Madrigal status and Nellie Gomez, their au pair, becomes the very first Madrigal without Cahill blood. Amy and Dan get a hint that leads them to William Shakespeare in Book 10. Through a series of riddles, their next hint tells them to go to an island off the coast of Ireland, and the other teams track them down. Soon, all the teams are present, including the Starlings. Unfortunately, Isabel Kabra has already reached the center of the gauntlet and demands all of their Clues. It is said here that Amy was willing to make the ultimate sacrifice for her brother. The teams finally unite and defeat her. Since the teams don't trust themselves around the Clues, they give all of theirs to Amy and Dan. Because of this, Amy and Dan win the hunt the way the Madrigals would have wanted them to. They all make it out of the Gauntlet alive, and all the teams come into good terms with each other. They all return to their lives, but it is clear that it all has just began. It is shown that they returned to their normal lives in The Black Book of Buried Secrets with Dan starting middle school and Amy starting high school. They go to the graveyard to which their parents were buried after they died.There, they find a clue hidden in Hope's gravestone along with a coded message. It is shown that they went to Grace's bank account in Switzerland, and Amy sends a call to Jonah Wizard that the Vespers are coming.
