Rapture in Death is the fourth book in the series. The plot for this book centres around Eve's investigation into a series of unrelated suicides that are completely out of character for the victims. She is certain that something, or someone, is causing them, and is determined to figure it out.

This is the most outlandish plot so far. The technology used in this book is much further advanced than in any of the previous books, and is way ahead of where we are now. The story opens at an offworld resort, and heavily features VR simulations.

The story is overall darker than the previous ones, and it seems to take a little bit more to read, but it is still a great story, and great addition to the series.
