Missing Since Tuesday
by Sarah Hardie

It's the year 2009 in Wellington, New Zealand, where orphans Duncan and Sophia Grant live quiet, often lonely lives. He studies history; she struggles through a thankless government job.
Duncan meets a chatty, popular girl named Maria who is drawn to him just as he is drawn to her, despite their polar opposite personalities. Their fragile partnership is doomed from the start, and is shattered one day at Wellington's rugged south coast where Maria slips and falls into the violent sea - or so they think.

On his death bed, Duncan's grandfather tells him the secret of the rocks - they have the power to send people back in time and, determined to save the love of his life, a frantic Duncan, who is slowly losing his sense of reality, finds himself in the midst of World War Two.

Worried for her brother, Sophia follows and begins her own love story with Arthur, a railway worker who has also lost the love of his life, though to murder, not accident, and once their paths cross, powerful secrets are revealed that will test their relationship and their individual lives, which are changed forever as they all chase love through time in a world turned upside down by war, racing against the clock to bring everyone back to where they belong.

This is the blurb to my first novel-in-progress... what do you think? Would you read it?

The path I choose to follow

Lately I've been thinking about my novel, Missing Since Tuesday a lot, and have found myself getting bogged down with ideas; so many ideas in fact, that I feel I'm lacking a clear direction and it's going to end up too full of observation and become boring.
Don't get me wrong, I have pages and pages of great writing (well, I think it's great and all the people who have read it think it's great...) and a head full almost to the brim of ideas, but it's just too much sometimes!
The main problem is that every time I go on a research mission, a new strand gets added to the story - I find out about an event I didn't know about like New Zealand's Centennial Exhibition at Rongotai in 1940 and I see my characters there socialising, talking about the war and such, and then the whole story ends up changing around it and I can't settle it for long enough to get past chapter six (I've written six chapters in order, but I do have about fifteen more that are scattered randomly and I'm not sure where they fit).
With so much history, so much information, it's hard to find a middle ground - to know when to draw the line and get to the point of the story.

So to all you writers out there reading my blog (thanks for reading!), what would your advice be? How do you draw the line on information and how do you settle on one direction for your story so the writing flows smoothly instead of changing all the time?
