- There are 4 main characters in this book, Indiana Jones, Henry Jones Sr., Elsa Schneider, and Walter Donovan.
- Henry “Indiana” Jones is an archaeologist as well as a Professor of Archaeology at the fictional Marshall College in Bedford, Connecticut. Indiana is the main protagonist of the story. Indiana is constantly on the run from those who wish to sabotage his archaeological plans and discoveries or from those who wish to end his life. During his various ventures across the globe, Indy reconciles with old friends, makes new friends, and finds new enemies.
- Henry Jones Sr. was the father of Indiana Jones as well as a Professor of Medieval Literature. He was hired by Walter Donovan to recover the Holy Grail, a Biblical artifact said to give eternal life and limitless healing. He joined his son Indiana for the quest for the Holy Grail.
- Elsa Schneider was an archaeologist loyal to the Nazi party. One of the antagonists of the story, she was assigned the task of retrieving the Holy Grail for Adolf Hitler and worked with Indiana Jones and his father to recover it. Her secret loyalty to the enemy put her life in danger.
- Walter Donovan was a wealthy American industrialist and collector of antiquities who allied himself with the Nazis in order to obtain the Holy Grail, which he sought for its fabled gift of eternal life. He was the main antagonist of the story.
- The story is set in 1938, a year before the start of World War II as well as the time of the rise of the Nazi party. Adolf Hitler orders his armies to retrieve the Holy Grail, the cup of Christ which had rumored capabilities of eternal life and limitless healing. Indiana Jones is brought into a new adventure after millionaire industrialist Walter Donovan’s lead researcher disappears mysteriously. The lead researcher is none other than Indiana’s dad, Henry Jones. Meeting up with archaeologist Elsa Schneider in Italy, Indiana discovers the location of the Holy Grail. He soon finds that his father was kidnapped. When Indiana and Elsa find Henry Jones, Indiana discovers that Elsa and Walter were double agents. If Indiana will obtain the Grail and gain eternal life for himself and his father, it will give the world a future of light. If Adolf Hitler and the Nazis triumph in the search, they will inevitably prevail in the ensuing world conflict.
- The main conflict of the story was about Indiana, his father, and other friends made on the adventure beating the Nazis to the Holy Grail. Despite the fact that all parties arrived at the Grail site at the same time, the task of finding the actual cup in a display of many fake Grails was presented. The fake Grails had opposite effects on its claimer than the real counterpart, instead ending the retrievers life painfully. The large possibility of accidentally claiming one of the fake cups put the Nazis’ lives in grave danger.
- I enjoyed this book because I had knowledge about the Indiana Jones stories. Since this book was written after the Indiana Jones film of the same name, it was easy for me to follow along the story as I had previously watched the movie when I was much younger. Adapting an adventure movie to a book had one key advantage, which was the fact that the author could further explain plot points or give the characters in the story more development. Reading the book reminded me of my first time watching The Last Crusade.
