I am totally in love with series'. I do try to read them in order, but I won't put off reading a new story because I haven't read the prequels. (I like instant gratification.) For example: Nora Robert's Remember When is what got me reading her In Death series. I haven't read all of the earlier books still, but I read every new release almost immediately. I don't mind multiple author series, like Raintree trilogy by Linda Howard, Beverly Barton and Linda Winstead Jones. I love to reread my authors. My family jokes that I could start a library with my collections. I usually reread series when there is a lull in new publications by my favorite authors. (They all seem to publish within a few months of each other in the spring and fall, with lags in between. I have moved to mostly ebooks now, however. I like the fact that they are more easily stored. They take up a lot less space on my bookshelf (ha ha).
