I know I've mentioned this somewhere before but has anyone tried Patricia Cornwells Scarpetta seriese...I found them addictive and have read the whole seriese. some let downs here anfd there where I think the author had a silly moment but very good reads that have individual stories to the book but a constant story of the characters lives running throughout the seriese that keeps you hooked.
May be worth a read if you like Crime/Thriller books

If you like easy summer reads to make you laugh Sophie Kinsella Shopaholics books are very funny.
Books from ages ago that had me hooked were the tolkein books Lord of the Rings seriese and The Hobbit. and Virginia Andrews Flowers in the Atic etc...I was 14 when I read them and so disappointed when the movie came out.
