The Invasion by K. A. Applegate

"The Invasion" is the first book in a science fiction series that introduces readers to a group of five young friends who stumble upon a crashed alien spaceship and are given the power to morph into any animal they touch by a dying extraterrestrial. This power is a weapon against an unseen invasion by a race of parasitic aliens who secretly take over human bodies. The friends, now with the ability to transform and the knowledge of the alien threat, become the unlikely defenders of Earth, facing not only the challenges of battling the invaders but also the moral dilemmas and the strain on their personal lives that come with leading a double life as part of a guerrilla resistance movement.

The 8545th greatest book of all time

Ranking Details:

Our ranking system awards points to books based on their appearance and position on curated lists. Here's how it works:

Unranked Lists: For lists without specific rankings, each book receives points equivalent to the list's weight. This approach recognizes the book's inclusion on prestigious lists.

Ranked Lists: Books on ranked lists receive points in two ways:

  • Base Points: Initially, every book is awarded points equal to the list's weight, acknowledging its significance.
  • Bonus Points: Additionally, books earn bonus points based on their ranking. The total bonus pool, equal to 100% of the list's weight, is distributed among the books, with higher-ranked books receiving more points.

Exponential Distribution: The distribution of bonus points follows an exponential model. This means the top-ranked book (#1) receives significantly more bonus points than those further down the list (e.g., #100). Our algorithm ensures that higher placements are rewarded more generously, reflecting the achievement of a top rank on any given list.

This scoring system ensures that each book's ranking reflects both its presence on multiple lists and its positions within those lists, providing a comprehensive measure of its acclaim and popularity.

Total Points: 54

Since this book was first published in 1996, there is a penalty of 35.2%. The age adjusted score is 34.99.

This is to prevent newer books from reaching super high on the ranked list of the greatest books of all time. The greatest books should also stand the test of time.
