I don't think it's writer' block, I think I'm just lazy. Sorry, folks, Linnet (of Serendipity) is in chapter 3 and hasn't progressed for weeks. I'm working on a fantasy - 'Dryad' - but am not getting much writing done; rather vegging out with other people's work, which is enjoyable; there's some really good stuff out there just now. Besides, it's year-end exams and I have a fairly full schedule of invigilation.
Thank you all those who've read Serendipity and thanks to all the anonymous comments - I just wish I could respond in person.
