FEARLESS (SERIES)  BY FRANCINE PASCAL ( CREATOR OF SWEET VALLEY HIGH)

Set in New York City, Fearless tells the story of 17-year-old  Gaia Moore, a girl born without the fear gene. The final book in the series was published in November 2004. Books 1-31 are available in both the British and American covers but 32-36 are only available in American ones. There are 36 books in the series, though two additional "super editions" give extra information about the past and present of the series.

The first novel starts of in New York, and Gaia has just moved in with her new foster parents and beginning to attend a new school. She has a very unique personality, and bitter sense of sarcasm. At night, she goes walking through Washington Square Park, purposely waiting for muggers to take advantage of her because she's a girl. When they do, She takes advantage of her lack of fear gene and training in many martial arts.

It is later discovered that Gaia has an extremely complicated family history. Her father, Tom Moore, is a CIA agent. He has a twin brother, Oliver Moore. There was a complicated love triangle between Tom Moore, Katia Moore (Gaia's mother) and Oliver Moore (most of this family history is learnt in Special Edition 1, "Before Gaia"). This love triangle results in Oliver trying to shoot Tom, but instead, accidentally killing Katia. After this tragic event, Tom realized that Oliver would continue hunting Gaia if she stayed with him, and forced himself out of her life.

The main plot around all the books is that somebody is after Gaia. In the first lot, Oliver (or Loki) is trying to win Gaia back and make her trust him. It is later understood that he does this because he loves her and believes she is his daughter. However, he goes about it the wrong way, and hires CSI agents to track her, and even goes to the point that he kills her friends because he wants her to only be close to him. After he realizes Gaia will never trust him, and Tom comes into the picture, he chases Gaia down to try and figure out how she is fearless, and to try to do tests on her to possibly create another person that lacks this gene (cloning). After a stunning event, Loki goes into a coma. When he wakes up, he realizes what an evil person he was, and all he wants to do is help Gaia.

This is when the RODKE family comes in. The Rodke's were a famous family that owned Rodke pharmaceuticals. Gaia became friends with the two younger children, Liz and Chris Rodke. Eventually, it was found out that their father was trying to get Gaia's DNA and create a drug called "Invince." He made Chris sell these drugs on the street, to see the side effects. His plan was to later sell the improvised Invince to the army.

I love this series, although after a while it just seems dragged out and like the author was trying to get as many books possible out of it!
