What's the Name of That Book??? discussion

This book about this girl who lives in the future with her mother and stepfather who is a scientist at a lab that I think studied people who could move things with their mind. this girl finds out that she was created from a frozen embryo that was made in the 70's because she has a sister in the past that had a strong ability for ESP and even made a paperclip vanish, But some how this girl pulls the paperclip through time and it appears in the lab with her.

*****SPOILERS******
Well the girl starts to do research to find out what happened to her sister from the past and finds out that she was murdered. She also has a brother from the past. So somehow she goes into the past to save her, and after awhile tells her who she is. They become the best of friends and a mystery from the future is solve (why a skull was found in a cave). The girl also goes to a physic in the past and tells her that the frozen embryo she sold to the lab, was a girl that she knew (that had jagged pupils) and was unhappy in the future, so the physic goes and has the embryo implanted in her and the girl is born and is happy growing up in the 1980's.
