Sam and Julie are identical twins. One is an artist and the other a scientist. Julie has been doing research into looking into memories and people's mindscapes while Sam is living in Paris, painting and living impulsively. They lost their parents early and were brought up by their uncle.

Sam is found in her apartment in Paris, unconscious and her rooms ransacked. There's no obvious reason for the unconsciousness and Julie decides to investigate the only way she knows how.

What she finds could shatter her life.

It's interesting, the characters are different and the tech isn't explored in depth but assumed, meaning that it doesn't come across quite as dated as some descriptions of virtual worlds from the 90's. Enjoyable but somehow lacking a bit, the ending felt a bit of a letdown, I did guess some of the mysteries quite early on. ( )
